From the photos, it appears the frog is actually set too far back. I think the iron is hitting the boss that the frog aligns on instead of sitting flat against the frog face. This is causing the edge of the blade to rotate out and forward.
I would completely remove the frog and clean out any chips, rust, debris that would cause it not to sit firm on the shoe casting. When re-installing it, move it about 1/2 the distance you have now closer to the back edge of the mouth. The front of that boss that the frog aligns on has to be below the surface of the frog when you tighten it down to solidly bed the iron.
The other thing I see is that the flat edge of the iron appears raised on the front 1/8" and maybe even bent forward (altho that could be camera parallax). The fact that it has enough ridge to hold sawdust behind it is definitely not right. The front of the chip breaker should set pretty close to the area where that "ridge" appears to be, and maybe even a bit closer to the edge. If it is in fact bent forward, the iron probably has lost its temper, and is not hard enough to hold an edge. May need a new iron. (HD has some $3 2" Buck Bros irons that will fit, but will need a lot of work flattening the mill cutter marks out of the "back" before you will get any fine shavings from them. After that work is done, they hold an edge Almost as well as new Stanley irons IMHO).
You have some work ahead of you flattening that iron and getting the pits out of the edge. When finished, that back should be shiny as a mirror and completely flat (Yeah, the front of the iron when installed in the plane is actually called the "back". Just another term that all the old galoots use to confound those of us whom try to follow behind them!).
I think with the iron flattened and the frog moved forward about 1/64" to 1/32" will solve the problem without doing any filing on the mouth.
Hope this helps, and welcome to the world of old, used, abused hand planes.

PS: The markings on yours are identical to the 5C Bailey that I have. Mine is missing the lateral lever and has a cracked base on the front knob. Here is a picture of it with the Buck Bros iron I radiused for when I use it as a scrub plane. It works well as a Jack, too, with the regular blade.
