They built the styled B with metal seat from 1939 to
1946, for the 1947 model year they went to the
square cushioned seat with the battery under the
seat.
John Deere started there new model years in August.
If you have say for instants a 1941 model it was
built from August 1940 to August 1941. I hope this
helps you out. There are books that tell by the
serial # what year your tractor is.

The maincase casting number is a good start to separate 39-40 from 41-up. Tag shouldn't be brass unless it's a replacement tag. Should be aluminum or steel. Unless the tag is just completely obliterated, it can usually be read. Rub tag with a cloth and some solvent, or other mild means. Nothing too abrasive, anything that leaves it scratched up will only make it harder to read. Look at it with a good magnifier and a flashlight held at different angles. Sometimes rubbing some darker compound (ink, graphite) into the numbers on a clean but worn tag will help them show up.
Being able to read the tag is your best bet to an acurate outcome.

Forgot to say the maincase number is ahead of the pulley and should either be B1300R or B1840R. There will also be a heat code along with this number, but it is of little use in the styled era.
Reading your tag is still the best bet if there is any way it can be read. It's the birth certificate.

First off, are you sure it's a brass tag, because it shouldn't be? Should be aluminum, or steel during part of the war. The steel tags are frequently hard to read due to the fact that they were not as deeply imprinted to begin with. Both tags will "seem" magnetic due to the cast iron underneath, but the steel tag will be "very" magnetic, and usually rusted. The aluminum tags have a white metal look to them and a different sound when tapped on. The aluminum tags can usually be read from the backside but not the steel ones.
To split it between 39/40 and 41 and up, what is the maincase casting number? That will possibly eliminate the first two years at a glance.

Take a look at the list below and see if you can come up with a serial number close.......Rich

You can add pictures right here. Just go to the bottom of your "reply" box and select "upload photo" then just upload the photos you have on your computer to the posting. I'm not well versed on it myself but it will kind of lead you through what you need to do. Others on here are far more adept at using the upload features than myself. Ask for help if you need it on that issue and I'm sure you will get some help with it.
Well I see from the pics that it appears to be between 96000 and 136661. This is all of the 41/42 model year and just the first few hundred tractors of the 43 model year. I see it has a powerlift that looks like it could be original to the tractor, at least been there for a while.
If the tag on top of the powerlift is still there and legible I have a list of a few powerlift numbers matched to tractor serial numbers that might narrow it down a little more. The tag is right on top of the rockshaft housing, ahead of the pedal spring. It will read PL-B and probably five digits.

Harvey,
The early '47 models still had the steel pan seats. The changeover to battery box seats was at ser# 201000.
From '39 to '48 the model years began on 1 July. The year ended on 30 June except in '48 when Deere went back to a 1 November to 31 October model year. The '48 model year was 16 months long.

I'm not the best on them, but it looks like a 45-46 to me. Note the battery box in front of the pedestal, the cast wheels and longer hoodline. It's not a slantdash, and it's not a cyclone. Yet it had a spring seat (replaced at least once). And the tag should be readable- it's right where it should be, and it looks like brass.
Unless a lot of parts have been swapped, it is between 96000 and 136661 (41/42). As I said below, the powerlift number could narrow it down some more. I don't know of any other parts that will narrow it down farther than that.
Where you located, the background looks like Colorado?

As per your probable serial number group, the muffler is an AB2700R and the pipe is an AB1526R. I will tell you what everyone is going to tell you, "get a parts book". It will save you all kinds of grief down the road and is probably the one most important thing you can have for your tractor. You can download one for free from JDParts. I have paper manuals myself, but others on here can tell you how to download what you need from the JD website.
Post back if you ever determine the serial number from the back of the tag, or whatever.
Enjoy your tractor.
