Who does case hardening? I'm helping a friend clean up her late husband's estate and he had a Pedersoli rolling block kit partially finished. I'm finally getting the parts fitted, but need a good source to have the action, rolling block, and hammer case hardened. This is a black powder only gun, should the action pins be hardened also? I've heard Doug Turnbull Restorations is good, but wanted some input from the AR community before deciding.

Just down a couple of posts...

I contacted Classic Guns yesterday evening via email and had a response this afternoon.

I have had Turnbull do color case hardening on several double rifles and his work is always perfect.
