The lenses don't go on that camera. They go with a pacemaker (post WWII) speed graphic. The 5x7 would most likely use wooden lensboards. (which you can make yourself if you wish to use it) Looks like a decent haul. The speed graphic is probably 1930's or earlier. You'd have to compare it with photos of others online. I have a 4x5 speed of similar vintage that's late 20's early 30's.
