Hi John,
If it is from a Tech. 111 then the lens would date from the early fifties. Not that Schneider changed them all that much (apart from coating improvements) over the years. The format is 9x12cms, or 5X4 inches, making this a short tele....approx. 135mm in 35mm terms. Others may know more about it's optical make-up, but I'm guessing that it is a four glass design, and the tele designation means that it doesn't need anything like 360mm of bellows draw to focus on infinity, much less in fact. I have never used this lens, although I used to have the 240mm version, which was an excellent lens.
The old compound shutters in this size make a wonderful noise when fired, so even if you don't have a camera to put it on, you can have fun just firing it off!
I don't know which cameras the technika boards fit (apart from Technikas) but I think that Wistas may be the same.
