1933rl
only a couple of guys make anything for machines that old, and the ones they make are exact - as a gentleman's agreement when its judged that info is forth coming
to me they look good this was my 26 I sold a few months back we bought in a chicken basket 8 years ago
It looks like my by spent most of its life in Germany - it eventually surfaced in East Berlin (DDR) in the early 60s.
Someone has spend a few bob on it as the renovation work is museum quality.
Kindest regards,
Bob
Bob, welcome to the forum. I see a few things not consistent with 1933 but before we get into them and before we get onto production figures, can you clarify something please because Im a bit confused about the ID you provided for the bike. You said its a 1933RL but you say the engine number begins with 33D. Are you sure about the engine number?
As a Flathead 45ci Solo, the Model D was introduced for 1929 and it continued thru 1931 which was its last model year, AFAIK. The generator was attached vertically.
The Model RL was introduced for 1932 and it continued thru 1936. Therefore I wouldnt expect to see an engine number beginning with 33D.
Can you post a photo of 33D**** please. Thanks.
Did you check the belly numbers? If youre not familiar with them, look under each crankcase half near the outer edges and somewhat toward the front. The belly numbers may be formatted similar to the following example: 33-1234.
Its interesting you mentioned that it looks like the bike spent most of its life in Germany. For 1933, H-D produced at least four Flathead 45ci models for Germany: 33REX; 33RLEX; 33RLDEX; and 33RESX.

Many thanks for replying to my plea for help.
I'm mainly a Norton bloke (although I also have a 1969 Servi-Car) and therefore have not much of a clue when it comes to the RL which I acquired a while back.
I've checked the engine number - 33D1990 - it looks original but will send a photo when I get back home. Will also do the same for the belly numbers.
The only data I have to work from is the East German (DDR) registration document which could possibly indicate that the bike had arrived in Germany prior to WW2 and ended up in the Soviet Sector of Berlin after the war.
Have you any other observations or comments.
Cheers,
Bob
I have a photo of that 33D engine number. I saved it a while ago but Im not sure where from. (Perhaps eBay?) The only other picture I saved is posted below. Notice the air intake/air scoop the bike had at that time. Also notice my red arrow. Above that arrow you may find casting number 112-322 and Ill come back to that later.

As I mentioned above, as a Flathead 45ci Solo, the Model D was introduced for 1929 and it continued thru 1931. The generator was attached vertically as shown below in the illustration from The Legend Begins (H-D publication #99403-93).

At least three other Flathead 45s were available in the D-series at one stage or another and they were the DL, DS and DLD. But that ended with 1931 models.
A lot of things changed for 1932 with the beginning of the R-series (R, RL etc). The generator was no longer vertical; instead it was horizontal as we see with your bike. Another difference was the frame and youll notice in the Legend illustration that the front downtube was straight for the D-series. But your front downtube is different and the change allowed the generator to be horizontal.
Your exhaust tailpipe is similar to the type first used for 1934 models but the cut at the end looks like it may be at the wrong angle. The toolbox seems unusual for 1933. A cylindrical one was used on 45s for 192930 but a wedge-shaped toolbox was used for 193134. The tank graphics arent consistent with 1933. Normally for 33 wed see Harley-Davidson but in smaller lettering and on each tank Id also expect what H-D referred to as an Eagle Head transfer. However, at times some features on export bikes were different to those used for domestic machines.
The main problem is that AFAIK there was no Model D for 1933. And your engine is an R-series as opposed to a D-series. R-series had a horizontal generator as I mentioned earlier and the left case had casting number 112-322. But the D-series had a vertical generator and the left case casting number was 112-29B (and it was in a different position to 112-322).
Also some characters in your engine number are not consistent with factory stamping for 1933. Your 3s have a vertical serif at top left but for 1933 Id expect 3s to be sans serif. Your 9s are fully rounded whereas Id expect them to have only a slight curve and your 0 is a lot more narrow than Id expect.
The belly numbers may tell us more about the model year of the cases.
Is the engine number on the East German registration document? Does the document say anything about RL? Did the seller explain why the engine number is stamped D?
