Looking for an engraver to engrave the caliber on a Smith & Wesson barrel, should also be able to reblue afterwards.

Roger Kehr's work is perfection, not sure if he can do the reblue.

Contact info ?

Alan Harton at Single Action Service can do it.

Gunsnith Jim Kobe handled both tasks for me, turning them around in a short time at reasonable cost.

Glad You found someone to do the job and you are pleased with the results.

For some cauht up in this same scenario..consider etching...when patiently done, it's very nice and you don't have to reblue afterwards.
