Thank you all for the inputs on the subject yesterday. Today I went to take some photos of the castings and to study the machine a little closer. On the engine I found 10 x 19 x W, which makes it a 1951, no problem there. I have posted photos of two L casting tags in the tractor photo section as I do not know how to post photos here. I now start to think that it could be a 1941 tractor with a 1951 replacement engine, or..
 
(quoted from post at 09:51:11 01/18/09) it's a 1942 with a 1951 engine. the bell housing month and day a backwards tho odd.

Could the tractor be European? They put the day first in Europe.
 
That's an excellent question! There were all the Bxxx British built and I've seen a few guys here with French Cs. It's either gonna be something like that or I note that October 17 fell on a Saturday in 1942 and wonder if somebody in the foundry might have been nursin' a hangover. Didn't they used to say you should never buy a car built on a Monday or a Friday? Think what Saturday must have been!

Any event, I'm lining up with the view that the chassis on this thing is a late 42 or early 43, with a 51 motor
 
The two L's are Aug 8 1942 and July 10 1942. The month and day are not backwards, unless what I am calling July is acutally 17, a little hard to tell. What is that part, I do not find the R1 part number in my M parts manual. Anyway, it would appear that the 1951 engine is a replacement. To confirm you might check some more codes. Look on the clutch housing where the serial tag is, or is that the 7or 17-10-1942 code?
 
I doubt if this M is British built in 1942.
The first British built BM's were not built in Doncaster until September 1949. Reference The Roar of Dust & Diesel, Mike Teanby.

CNKS your right more information is needed. Belt pulley gear box is more likely to be a 1966.
Need a cast number from axle housing. The dip in housing at left side in picture doesn't look like whats going to be a standard M housing. This is all I'm posting on this, you're on your own.
 
I've been sitting back and enjoying this topic.

For one thing, I would like to know where in the world this tractor is today. That might give some clues as to where it was built in the first place.

I don't know whether the things on the axles are date codes or not. For one thing, the one looks like "17110 L", not "17 10 L". The other one looks more like a date code.

The other thing is the "R" part number. There were no R numbers in 1942. If this housing was cast in the US, it must have been 1965.

In any case, it is going to take more information from the tractor (and maybe more pictures) to figure out what it is.
 
Jim, although "most" date codes are separated by "screw heads", as you know not all are. When I first looked at the date code, I thought it read 7 10 L with vertical lines between the numbers, now I'm not sure. But if it is 7 10 L, that and the other code on the axle housing pretty well match. BUT, I forgot that R part numbers were not used that early. In the M parts book none begin with 100 (if I'm reading the R1 part number right). Looking again, it looks like 1C0185 R1, which also does not fit any IH codes of that era. So maybe it is a British? tractor. This thread kind of opens a "can of worms". I think we need a picture of the whole tractor, maybe you or D Slater or someone can identify it.
 
Britisch Farmall's had the first year the US castings.Later on they used an hole diffrent system that always started with 700,701 and 703 numbers.Some tractors of 51 and 52 out of Doncaster are really mixed up with US and GB numbers.Really have know idea how it works.My '51 MV has all correct numbers and it's all W all over the tractor.So this elephant wasn't change during it's life.Except for all the "Industria Argentina" replacement parts and some strange original IH parts like an M front weight(With R number)
