All external serial numbers match, but I have not disassembled it to see if they all do... so assume they don’t for now.

That's a big thing to know before you arrive at any price conclusion. It may just be the photo's but your description says Lots of wear and I would want to know what the bore looks like before I would assign a price.
IMO $1000 could be reasonable ... maybe not too..more needs to be known.
Hugh could do some magic on the grips no doubt..IF they are matching? $65?
The repro mag is good for a shooter but one would want a proper period mag. $125-150
It's still a tough economy.
