Vintage lens question

[Jim Graves]

I have a Taylor-Hobson Cooke wide angle anastigmat 82mm f 6.5 series VII B ... works great in my Speed Graphic with the focal plane shutter but I'd like to include it in my backpacking kit ... but, it needs to go into a shutter ... anybody know how to go about that?

[Jim Graves]

I did check S.K. Grimes list of lenses to shutters but this one is not listed.

This is such a small lens that for 4x5 front-mounting shouldn't cause vignetting problems. Just don't cheap out and use the smallest possible shutter.

[Carsten Wolff]

I agree with Dan. I think Barbara told me once that the originals went front-mounted into an Epsilon-shutter.....Frontmounted I would have opted for a Copal 1, or similar sized shutters, like a nice Alphax.
My 108 is now a Copal (Press) 0 affair, thanks to SKG. The 82mm should fit with a bit of effort into a Copal 0 as well.

They seem to be growing expensive anymore, but for a while you could buy either a 75mm ossiliscope (spelling?) lens or one of those Tominon Polarid lenses for a cheap price, take out the lenses and you have a nice shutter. I front mounted my RD artar in a shutter that way and it works great.

But do pay attention to the size of shutter - when front mounting, you need something bigger than you might think. for example, my RD artar needed a #3 shutter for front mounting, whereas for a "proper" job, a #1 shutter would work fine.
