I have an Agfa Rondinax 60 tank which I used for many years. Unfortunately one of the ears broke off the film guide, is there anywhere I can get a replacement, I would even consider buying a complete tank. hope you can help, thank you.

There does seem to be a shortage of film  guides. They are often missing from tanks sold on eBay and can be broken fairly easily. Any chance of anybody making some by 3D printing?
