Touch up blue for 1960s Colt

[SIGSHR]

Any suggestions? This revolver was improperly stored, needs to be reblued (down to bare metal) over 2 chambers and some other spots. It has the old
Colt almost black finish.

 

[Bill DeShivs]

Don't try to touch it up. You won't be able to come close to matching the original finish. Contact Colt or a professional refinisher.

Either leave it the way it is or have somebody really good redo the whole thing. Otherwise it will look even worse than it looks now.
