350 vs 350b same or different?

[dillon45]

I have a chance to buy a 1973 JD 350 Don't have a serial number.
My question : is there a difference between a 350 and a 350 B ?
The machine does not have any decals that are visible and the serial
number tag is missing.

The owner is asking 3900.00 for it, which i think is a reasonable price
he states it has new rails.
If i could, i would like your opinion on this machine
Thanks in advance.

P.S. I was going to add a pic. tried but no luck.[/img][/url]

B model has reverser shifter on the LH side of the seat, straight is on the dash. Some other differences, but not earth shaking.
