I would really appreciate some help from the Ansco shooters. Tomorrow I am going to look at an Ansco 8X10 flatbed. Gray color, 12 in. f4.5 lens. Also has 5X7,4X5, and a split5X7 back(2x3.5x5). 8X10 and 5X7 film holders. It has F&R swing/tilt. Front rise. Anything not so obvious to watch out for ? Although the obvious sometimes escapes me, perhaps the obvious should be listed too.
