From what you've said it sounds to be a similar size to my south bend-ish lathe (a Canadian copy). Took two of us to carry it up out of the guy's basement when I bought it. Around 100lbs I'd guess. Tailstock and Chuck removed but headstock and carriage left in place.
Try looking on lathes.co.uk you'll probably be able to identify it. Spindle nose is 1 1/8" threaded.
