Hi, I won a battered old enlarger on ebbewatsit the other day. Mahogany quarter plate with a steel lamp and condenser housing, nice maroon leather bellows. A nicely built piece in it's day, it is now very rough; a rebuild project for a rainy day one winter I think... Thing is, it is stamped T.S & H. Pat. 22469 (well, it has a printed white bone disk embedded in the woodwork, actually). It's in Britain, so British companies are most likely. I've had a good Google, but can't turn anything up. Anyone want to take a guess who T.S & H might be?
