Thanks, RJay, it is nice to have someone share my ignorance. I did check the Crescent brand names and that is not one of them, though I am not sure there is or ever will be a complete list.
"Wabash" was probably a store brand name. At one time, any store that wanted to order as few as ten guns could have the maker put any name they wanted on the guns. Wabash would suggest Indiana, but that doesn't help much.
I doubt that anyone would have parts for that gun or any diagrams showing them. If you want to try to make parts, I am afraid you will have to figure out what they should look like.
FWIW, that gun likely has zero value in monetary terms, so spending a lot of time and money on it would not be practical. If it has sentimental value, I suggest retiring it to a wall hanger status.
