Last B Serial number?

[Gordon S]

Can someone please give me the serial number of the last B that was made or tell me where I could find it? Also, is there a way to find out how many BW's were made with a water pump?
Thanks!

306600 had the first water pump and 310772 was the last B built, June 2,1952.

I know little about styled B's, but based on the info M.Hoffer gave you, and the numbers from the production log, and the math involved between numbers built per month and beginning and ending yearly serial numbers, 306600 should have been built around Feb 52. If that is accurate, there were 121 BW's (gas) and 6 BW's (all-fuel) built in Feb-May 52.
Having said that, and at the risk of being attacked on this, there are huge discrepancies between numbers built (according to the production log) and beginning and ending serial number ranges in the styled era. Unstyled numbers come out very neatly, at just a few tags missing per year, but styled are a mess. In 1952 there are roughly 6400 serial number tags missing from the serial number range on the model B! This makes it pretty difficult to estimate when a tractor was built based on the serial number.
In 51 there are roughly 4800 tractors (yes, tractors) missing. In 50 there are 3800 tags missing. In 49, 2200 tags missing. In 48, 7200 tractors missing. In 47, 900 tags missing (and yes, the short and long production years 47-48 have been figured in). In 46, 50 tractors missing. In 45, 200 tractors missing. In 44, 500 tags missing. In 43, 300 tags missing. In 42, 23 tags missing. In 41, 700 tractors missing. In 40, 1200 tags missing. In 39, 50 tags missing.
These numbers are all rounded off to the nearest 100 and are just for the B. A's are the same, if not worse. It is typically normal to have up to two or even three hundred tags that were scrapped in any given year, but I can't explain how you can have 7200 or 4800 more tractors than tags in a given production year. I would like to see Two-Cylinder or JD explain that one. Anyone got any ideas on this, I would sure like to hear them.
Sorry to use your post to sound off on this, and maybe I have overlooked something somewhere, but it is something that has bothered me for some time now.
Can you tell I'm a detail/info junkie : )

Thank you for all the detailed info! I just bought a B that has a waterpump and a factory wide front. The issue is, the serial number is not readable on the tag and was just trying to find out a little more about late B's.
Thanks again to all!

Sorry. Obviously 23 and 50 are not rounded off to the nearest 100, and 47 was not a short production year, 48 was a long production year at 16 months.

It's still in Minnesota.

A GURU,

When you say "production" year do you mean "model" year?

Yes. Production year and model year are the same thing. Any reliable serial number list is given in that manner. Unless Two-Cylinder has corrected their serial number list, it and this websites list are incorrect on beginning serial number for unstyled B's in 1938. The list gives 46175 as beginning serial number but it is actually 49301.
