Good info, thank you! I can barely move it so 88 sounds right vs for example 188. At a $1 a pound I'd keep it for at least a conversation piece, if it brought $400-500 then I guess I would sell. And no, no one was interested in it. Any guesses on age based on the serial number, so I can chat intelligently about it? Looks like a 156xxx I think maybe,... Really like that it is stamped. The top plate is quite rounded, but I wouldn't know good from bad. Thanks for your input. It's been holding up the floor in y bedroom for a few years.
