Any grips marked '2R' on the back are from the 'new' AJAX Grip Co' formed about 2010 (?).
The original went backrupt or filed for such around 2008 or 09. Original owner was Abraham 'Jack' Rosenberg,,that's where the 'AJAX' name came from.
The new comp is run by Ral Ritter and the son of the original owner, Paul.
Ritter did post on THR (The High Road) as 2RCO, don't know if he still does.
Don't know about stag grip material, but I'd guess in this political climate, stuff like that is off limits.
The orig company had a track record all over the map when it came to quality. Don't know about this new one. But you might check with the SASS people. I'd think they'd be pretty good customers for the products w/true feedback either way.
'bout all I know...
