That fork almost has to belong to that frame, the size is very unusual match and the crown is a match for the lugs as used on Paramounts.
The red oxide etching primer is a Schwinn hallmark, chrome underneath could be original and was just painted over at the factory well before the rattle can.
Also looks to me like there are two different coats of silver from the feathering I can see.
Is the chrome underneath polished, then scuffed, just polished.
Regardless of all this it may be too much for the co-op to do a deep dive on this. The group of buyers this would appeal to would want to do their own refinish.
It will need a good groupo on it to bring the $$$ you would need to get from the effort.
The size is a "big" unknown and may hamstring the whole thing the jump.
I hate to say it but efbaying the frame may be smart play. If I didn't already have a big silver one and 3 others I might be negotiating already.
If you wind it up and miss the mark, it will be time and $$$ squandered.
