Short story...
I picked up the S460 on eBay on the cheap since it wasn't listed as such. Landed a lower grade Hindu to trade and got the AB460 (SGC 30, now cracked) back with the deal. The big time beater Piedmont was in my H&S lot. Couldn't resist the laminated Hindu Red from Sterling.
Edited to add: And picked up the SC460-42 on BST!
