MR. Fricks,I have known Thad Rybka for about 35 years and he has made me more than a dozen holsters over those years.
Thads whole life style goes back to more primitive times. He has a phone,but only a few old customers have the number. If you wish to contact him, his snail mail address is:2050 Canoe Creek Road,Springville, Alabama,35146. If you write he will tell you how to contact him[send your phone number].
As you can see from the 1993 holster you have[ the 93 next to his initials on the back is the year he made it], Thad is a first class craftsman and applies a great deal of "gun savvy" to his designs.
BTW: if you wish to sell that holster please PM me. Hope this helps. Nick
