Gunsmith for Hi Standard revolver

[PWilliam]

Hi all,
I've got a Hi Standard Sentinel 22 mag that is misfiring. From what I've read this is not a gun to tackle yourself without the correct jigs and knowledge, so I'm wondering if any gunsmiths in the valley specialize in these guns.
Thank you.

If the Weapon Works fellas won't touch it, I think you're up-a-creek.
