I bought a 4x5 Cambo view camera from Ebay that I did not really need. I have a Toyo field camera that suits my purposes. I sent S.K. Grimes the larger Cambo lens board along with the smaller Toyo. They converted the larger board into an adapter that appears very well made. Quite pleased, good service, good communication.
Ditto what everyone else previous to me states. i had them retro fit a bino lens viewing devise to my Ebony and it looked like it was made at the same time the camera was.
sk grimes is a great place. they have made me 3 custom boards and a custom flanges. the last time i needed something done, i called, and adam said " come on down ... " ... i live about 30 mins away so i got in my car and drove to woonsocket ... then, he made the board for me as i waited now, THAT is service !
