4x5 Graflok back for 5x7 Tailboard Camera

thingiverse

I have this beautiful 19th century french tailboard camera. Unfortunately, it did NOT come with any film holders and my understanding is that it can be very hard to find 13x18cm holders that fit these old non-standardized cameras if the originals have been lost. But I really want to try shooting this camera since the bellows appear light tight, the shutter works, and the lens is quite clear. So I have remixed a 4x5 film back to, hopefully, work with this camera. I cant imagine anyone else would need this, but Im posting it here anyway. It will be neat if this works. This is very much a work in progress...
