I bought an 8x10 Korona camera a few years ago and started to refurbish the ol' thing. The standards seem to be in pretty fair shape, the only thing is - the rails are SHOT on this poor thing. I was curious if anyone knew where I could source a set of replacement rails? Do they have to be specifically made for the Korona or are there other rails for another antique 8x10 that would work? Any info is greatly appreciated!
