Looks like the triggers were bent forward. Probably to give the shooter a touch more LOP or to make them more comfortable with the stock drop.
I'd put those back to were they belong, put a stock on it with standard dimensions,,, might as well redo the metal & finishes too.
The tangs might be bent for the extreme drop. But putting those back isn't a problem if you're doing the metal up anyway.
Probably one of those 'not worth the investment' things but it's a neat gun and a nice project.
I could think of worse things to spend time on.
