[QUOTE=Speeding Big Twin;18943487]De hecho, puede ser 4 y el segundo número puede ser 5. A se muestra un ejemplo a continuación de comparación y notará que el 4 tiene la parte trasera abierta (a diferencia de la parte superior abierta ) . También observe que el 4 es sans serif. Este tipo de sans serif, espalda abierta 4 se usó en la posición de la década de BN para 1941–46.
En el caso de la izquierda, puede encontrar el número de casting 112-392 y un código de fecha de casting que consta de una letra y un número. Es difícil estar seguro de cuándo se lanzó el caso izquierdo, pero sospecho que alrededor de abril de 1945 y, de ser así, el código sería D y 5 (espaciado). żQué tienes?
D es igual a abril. Y en esta ocasión, debido a que los caracteres están espaciados, el 5 indica 1945.
NB: si esos dos caracteres no estuvieran espaciados (D5), entonces el código generalmente indicaría la transmisión en abril de 1950. Sin embargo, el espacio entre caracteres del código de fecha es algo que debe examinarse pieza por pieza porque las reglas no siempre son las mismas ya veces hay excepciones a lo que en un principio parecen reglas.
En cuanto al jefe del número de serie, parece tener algunas marcas, pero es difícil decir qué pasó. żQuizás limpiarlo y publicar otra foto? Además, como dijo John, muchos motores WLA fabricaron sin el resto de la máquina no estaban estampados con un número de serie.

] Hi Eric!!!
I have that case that is marked as G 1, what month would it be? year 41?
?

G'day Luis and welcome to the forum. Date code G 1 indicates the case was cast in July 1941. Heres an example for comparison.
I cant see anything wrong with your belly number (BN) and it looks consistent with factory stamping for 1942. I posted an example below for comparison of the first three characters. Notice your first 4 has an open back and no serif. In BNs it was used in the decade position for 194146.
For 1942 BNs in the year portion there were at least two types of 2: seriffed; and sans serif. Your 2 appears to be sans serif as Id expect at that stage of numbering.
In the BN sequence portion the 4 changed from closed top to open top either very late in 41 or very early in 42. Your 4 looks like it has an open top? Id expect it to at that stage of numbering. Notice its left stroke is slightly curved and there is a serif across the base.
Notice the 0 is oblong in shape.
The 5 looks normal.
The 9 is the usual round-back type Id expect at that stage of numbering. (For Flathead 45 BNs the 9/6 changed to a different style much later in 42.)

Hi Eric.
First of all thank you for your quick response as well as your experience.
Right, number four is open at the top.
Would we be talking based on these numbers of a type 1?
Youre welcome. We cant be certain what type, or even what model, your case was used for based only on the date code and BN. We need to examine the serial number although Im getting the impression your engine may not have one? But if it does, is it authentic? And what range is it? Can you post a partial photo please. Thanks.
Eric
Unfortunately, where you should have your engine number, it has a four-digit number that has nothing to do with reality, buy knowing that and that the right hull is marked 45.
Going back to the left crankcase 42, after investigating and thanks to Johan Willaert from http://www.theliberator.be/indexmenu.html we reached the conclusion based on a very close reference that it has and the low number of the belly 42, which could be a 42WLA48XX type 1
Luis, I mentioned above that we couldnt be certain what type, or even what model, your case was used for based only on the date code and BN. I also said wed need to examine the serial number (SN) but we now know your SN is not authentic.
You say your left case could be a 42WLA48++ Type 1 so Im getting the impression you may want to build the bike as that type (Type 1)? Is that your intention? If so, I dont think thered be any point doing that because you do not have an authentic SN. To build a bike as a 42WLA, regardless of Type 1-A or whatever, you need an authentic SN but you havent got one.
On the Liberator site the chart says Type 1 engine numbers were 42WLA1000-42WLA7000. But that is BAD info and it is NOT what Bruce Palmer said in his books. Palmer made it clear that only some, not all, SNs in that range were assigned to WLAs. Most SNs in that range were assigned to WLCs while some others were assigned to WLs, WLDs, WRs and Servi-Cars and that is because the engines for all these models are in the same family so their SNs were mixed in together.
Was your four-digit number stamped on an altered boss? If so the original SN could have been WL, WLA, WLC, WLD, WR or G for the reason I mentioned above. Or was your four-digit number stamped on a virgin boss? If it was, the left case may be part of a surplus engine that originally had no SN. Can you please post a photo of your four-digit number. Thanks.
Hi Eric.
I understand everything you explain to me, except for one detail.
If I am correct, the belly numbers reflect the year in which the engine was assembled and my crankcase has a number 42-4059, which would mean that it was assembled in 1942 and in that year only WLA and WLC were assembled, how could they be assigned to WL, WLD, WR and G?.
Attached photo of the engine number.
The bike in particular is a project, I bought it incomplete and given the parts that I have to buy, I would like to define how I am going to restore it and the idea was to WLA type 1 because it has the belly number 42-, with the intention of recovering it, which don't get lost along the way
being aware that it will not be a 100 points, nor a matching numbers, just that Eric.
I appreciate your answer, I'm learning a lot and I appreciate it.
Sometimes the BN reflects the year an engine was assembled but sometimes it doesnt. Your BN looks consistent with stamping for 1942 models but it may have been stamped in 1941. (Remember your case appears to have been cast in July 1941.) Production of 1942 models began around Aug-Sept 1941 and some were military machines while others were not because production of most non-military model Harleys didnt stop until shortly after the US entered the war.
For example here are partial photos of a 42WL and a 42G.
And even after production of most non-military H-Ds was halted, some were still available depending on approval by the authorities.
I think your SN boss has been altered. Compare its edges with my examples above. And there appear to be a lot of marks across the boss. Below is a virgin boss for better comparison. Notice its rounded edges and the overall appearance is rough-cast as opposed to the flat appearance your boss has.
Because your SN is not authentic and your boss appears altered, I dont think theres any point trying to build the bike as a WLA. The original SN could have been WL, WLA, WLC, WLD, WR or G and even if we knew which one it was there still wouldn't be any point trying to build the bike as it was originally.
The SN you have now (9151) may have been state-assigned as a way to identify the engine. Or maybe somebody made up that SN and stamped it themselves. Did you receive any paperwork with the engine?
Eric
Eric, your explanation is clear to me.
Buy the project with a bill of sale, knowing that the SN is not correct.
They are surplus (both motorcycles and parts) of what were once motorcycles of the Paraguayan police. I have more in sight for purchase and these other options if they have their correct SN in WL form, years 45, 46, 47 and a lot of spare.
Now with the expanded information on your part with this last message I don't know which way to go and I don't want to leave the project in the dry dock. He was unaware of the production of civilian models in 1942.
What date code do those two examples have that you quote from 42WL and 42G?
