I have a Super Angulon 65mm F8, currently on a Linhof recessed lens board, it came with a Technika 70. It's currently sticky at the slow speeds, and I'll have it serviced if I can use it on my Toyo 45A. I have a spare recessed lens board for the 45A, but it has already been cut for a larger Copal 0 shutter. Is there any easy way of adapting this recessed board with a 0 hole for a 00 lens? I know the lens doesn't quite cover 4x5 , but I would accept minor vignetting in the corners with no movements and take that into account when composing an image. Is it possible to obtain new blank Toyo lens boards, they are 110mm square. I'm in the UK, so local sources would be best.
