Parts resources

[Roger Smith]

Hello folks
Couple days ago I added to my large format collection.
I had ( still do ). Graflex 4x5. I added a Ansco studio portrait 8x 10 with most of the parts to the 5x7 back and a Folmer Schwing model #8A ( I believe) 8x10. The two more recent cameras need a few things to be complete. I am hoping to get some direction for research and parts resources. A source for positive identifications would be great too. The Ansco I took apart , clean and it back together. The Folmer is missing the gear assembly off the front standard that raises and lowers the lens board holder so I need to find that before it’s done. The first photo is the Ansco. The second is the 5x7 back. The third is the Folmer
Thank you
Roger
