Jack,
Very nice! I have a Ruger BH .45LC that Hamilton Bowen did a complete makeover on including case hardened frame. I opted to do the grips myself. I ordered a pair from Ruger's OEM supplier out east. I'm sorry but I don't recall their name. I called Ruger Customer Service and they gave me their name and number. You might try that route or Eagle Grips.
Nice job and good luck with the hardware.
P.S. You might try some Ren wax on the grips after they're thoroughly dry. I think you'd like the look (and if not, you can wipe with a little turpentine and slackum over it.)
Phil
