B & M Hydrostick transmission(?) Transmission has stickers, some linkage and torus that all say B & M. It has been sitting for many years and will need a complete overhaul prior to use. Trans is built on a G & M Hydramatic slant pan automatic, possibly from a 1956 Oldsmbile? You tell me. Transmission will have to be picked up, it is very heavy!! Great transmission for your nostalgia Gasser!!
