Wow. That's a lot for the stocks. I don't think I paid much more than that for the entire gun in the box years ago.
And it's still unfired....
Added: I suspect the value will be in the $750-$800 area even with the incorrect stocks. Most of the attention with Colt 22 revolvers is focused on the Diamondbacks (DBs) and you can find OMM's that are priced pretty fairly in comparision to the DB and probably shoot better to boot.
