The State of Maine No. 3494-275 has three variations. The only one of any consequence has the "B.A.R./3494275" with no line under and line overscores. This variation (A) is more difficult to find. Produced between 1956 and 1958, with Type IIB bodies, Multi-Block doors that were created specifically for the No. 6464-275, and painted WHITE and RED stripes on a BLUE plastic body with BLACK and WHITE heat stamped lettering. Came with bar-end trucks and later editions would have tabbed couplers.
