Graig Spegel doesn't have a website and as far as I know he handles every thing by phone and for the life of me I can't find his phone number right now, but I will eventually.
Right now he has some surplus grips for sale on pickagrip.com, no waiting and they may have what you are looking for. I bought two sets last week and they are beautiful and a work of art.
I'll keep searching for that phone number.
IN GOD WE TRUST,
BUT KEEP YOUR POWDER DRY,
JUST IN CASE!
