It's a T70B. I considered that someone might have put an older T205 serial tag on it but the tag is from Panzer Products (Virginia Metalcrafters). T205s were out of production long before Metalcrafters bought them. The 2 is a misprint.
I bow to those that know these tractors. My 1st thought was it was a B, but that didn't fit with the "20". We've all seen mis-stamps of numbers on ID plates before, so this must be one of them.
