This has Greg’s 1-1/4 stock rim with the cup/shank/throat designed exactly like a Warburton 4GS tenor piece. All one piece and in the regular weight blank. I’ve moved onto a wider Elliott 112 rim and will not use this anymore. Perfect for those bass bone players looking to double on tenor and not having to go smaller. Has only my last name stamped. Asking $150 shipped. Thanks!
