I just picked this camera up on Ebay and I'm looking for photos of one with a ground glass back. The seller thought he had one for it but it was a totally different one than this camera took. From what I've been able to find out via Google and APUG archive is that it took one similar to a Graflex back but I haven't been able to locate clear and bright photos of the rear of this camera. Any assistance is greatly appreciated. I bought this camera because it was made here in Toronto and I just wanted to preserve a piece of Canadian Photo Heritage.
