My Crown Graphic fell off my tripod while I was adjusting the Kalart with the cover off. The top L plate with mirrorr attached has broken. Is there anywhere I can get a spare one to replace this?
Urgent as this is the only thing wrong with this lovely example, though have been buying several off ebay thanks to $-£ exchange rate! Would be grateful for advice!

My guess is that there are some spare parts and old range finders out there. What model Crown Graphic, and which model Kalart are we talking about? Some serial numbers might help. Was it the "standard" Graflex configuration for that model?
