I have asked about these planes previously but have since pieced them together better and taken more picture.
There are four planes. Two #4s, one #3, and a #5(or 6?).
First up is the one in use, a Stanley #4 I think? I had cleaned the whole thing up pretty nicely and it was working pretty well until tonight when I knocked it off the bench. The blade got bent quite a bit, having trouble getting it to sit nicely on the frog now. Any tips on flattening?
Also I found I'd been using the lever cap from the #3 all along. I think this cap is the one that goes with it but I can't get it to tighten, it just barely locks. I can't drive the screw any further in, not sure if it has bottomed out or if the threads inside are locking (the screw threads are nice and clean).
