This is my second attempt at using a Magic Latern lens. This one is a B&L, part of a pair I bought at the Photographica show last month. I think it's pretty close to the 14" that Jim was using. Under the B&L info is the name "T(F?)olson Manufacturing, Orange __ . The info is not engraved on the barrel, but printed in the deteriorated top-coat on the brass.
The figure in the image is about 4" tall. Scanned contact 4x5 print, quite over exposed. Slow hands, first try.
