The State of Maine No. 3494-275 has three variations. The only one of any consequence has the B.A.R. with no line under and 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.
