wollensak 4" (101mm) ?

[Brad Bireley]

I got a wollensak 4" (101mm) for a couple bucks. What is it for?
It's mounted on a Alphax heavy duty shutter in a round lens board.
Thanks,
Brad

Likely a 2x3 Graflex or similar, but it could be used on any pretty much any medium format camera. It won't cover 4x5 without vignetting. I'm pretty sure that my Crown Graphic has that same lens mounted right now...

It could have been used as an enlarger lens also. Pat
