Is this a modified knuckle or pan straight leg frame, engine is long gone, brother of the deceased owner said it had shovel motor in it at one time, any info is appreciated.
Die number 4 on the front engine mount puts it in the mid 40's somewhere. Die number 3 on the rear mount comes up as 44-45. The upper engine mount being a straight down tab (assuming its not modified) is either a knucklehead or a big twin flat head, no other choices and no way to tell which as the frames were the same. The die numbers on the axle clips aren't visible in your pictures.

There are similar forging and die numbers on the side of the neck as well if you want to post them.
Do appreciate the info, I’ll scratch around on the frame and see what else I can come up with, this is one of those instances where I purchased some stuff out of an old shop and the guy knows I tinker with bikes and he said take it or it’s going to scrap, I realize it’ll never be restored back to original and I have no intention of building a hard tail as my body wouldn’t allow it, but I’m interested in what it actually started life as whether it ends up hanging from the rafters of my shop or passed on, again, thanks.

It is a frame. An open mind a welder and some cash it could be amazing.

the original steel used in the frames was braised in place as a memory was found when too much heat is applied welding them - asking a novis to weld a 6000 to 12,000 dollar frame as a complete real unit is something of a mistake
at one time it did not matter but today effing it up even more is very expensive - the last 1941 chopperized frame we had repaired by the right guy was almost 7 thousand to repair - in the end a correct machine is 6 figures today - not really doing it right is a very stupid mistake
The UU I've seen on 47 and some 46 bikes. The axle clip numbers say 1947 in the book I have. Maybe a fluke but the axle clip examples I've seen often seem to be the ones that narrow the year down.

Your help narrowing down the year is greatly appreciated, now to think about what to do with it.
Modified knuckle frame or ?
