Welcome to the Forum!
Iowegan hasn't posted here in a LONG while.
If you post a pic of the grips, we might be able to help.
OR,,,, maybe it was on the other Ruger Forum,,, (rugerforum.net)
If you are looking for a set of custom grips,,, we have some excellent grip makers here.

All come to mind immediately.
Cary has a web site, and Zane of LSCG has many pics around. 41 has info in the "auction" section I believe.
