I would keep that one. Don't see many vintage without the lock 2 1/2" 686's for sale and it being a -4 production. It looks to be in fine condition. In these times it would be especially hard to find another one at anything close to a reasonable price. I agree with $1000+ value. In my area (NW LA.), the pawn shops and gunstores would probably price it at between $1200-$1500. Good luck with your decision.
