Re: 4x5 Fisheye - was Simonturnpike ford

[Glenn Barry <bonza1@xxxxxxxxxxxxxx>]

Hi Steve,

I didn't remove the mount from the front panel of an RB, I removed the 
entire front panel, shutter cocking mechanism and all, then modified it 
so that I could cock the shutter from outside of the panel. I would have 
bypassed the arsat route altogether had I been able to find an RB 37mm, 
but as luck would have it, just when I finished the Arsat adaption one 
turned up, but the cash was gone by that stage. C'est la vie.
