Shooting from the hip here. I'd say your frame is 20's, maybe earlier. The frame you just put up looks Schwinn built and maybe early 30's.
My 34 Schwinn built Ranger has a similar stamp, but starts with a 5.
So I'm thinking earlier 20's and early 30's.
All you have are frames. These parts are going to cost loads more than complete bike cost, so do it for the fun/passion. Good luck and see what others chime in with before you start buying parts.
