I recently picked up a 5x7 Linhof IV Technica on Ebay. Originally when I made the purchase I was promised 2 lensboards. The seller after the auction could not find the lensboards so now I am sort of scrambling trying to find some. I have a few questions hopefully the knowledgable people of APUG can give me some advice.

1) Any ideas where I can find 5x7 lensboards for the linhof?
2) Read that the Linhof III 4x5 lenboards are the same size. Will they work with my camera? Looked for those on ebay with no results also, where can I get them?
3) Been reading a lot about an adaptor board that will allow you to you to mount a 4x5 linhof board on a 5x7 camera, anyone know where I can get one of those?

Thanks very much any responses are appreciated. Gerry
