what's this shutter?

[jp]

In the lens with a cord attached to the release? Is it a little packard in a recessed lensboard with a dial of some sort on the side or something different?

It's a roller blind shutter...sort of a cross between a packard and a focal plane shutter.

Most likely a Thornton Pickard.

Never mind the shutter. I want a pair of those wolfman gloves!

He almost looks as if he's on safari hunting lions.

Those are pretty good mittens/gloves. I'd say if I had them I'd have to use LF since they'd get in the way using a TLR (been there done that), but TLRs weren't likely around when this photo was made.

I think he is on safari for walrus or polar bear... perhaps penguins.

Most likely a Thornton Pickard.

definitely a T-P shutter Brian

This picture sent me on a little google chase, resulting in the discovery of the publication "The Telephoto Quarterly" in google books: http://books.google.com/books/about/Telephoto_Quarterly.html?id=u84aAQAAMAAJ in which I learned that most likely what we're looking at in the photo, behind the shutter, is an early tele-converter, comprised of a negative lens component and an adjustable tube to vary the effective magnification of the system. Though I knew about negative slip-on attachments (the same as supplementary close-up lenses, only the opposite) for changing lenses in to longer focal lengths, but not about early teleconverters.

I wonder if any of these things still exist?
