Okay, this doesn't help the HBB strap search, but APbands seems to have mimicked the HBB "gummy" finish, maybe exactly. I don't know if Jacob can get his hands on this type of treated hide yet, or maybe he already has it.
"This beautiful strap is manufactured from the finest Louisiana Alligator hide which has undergone a weathering and treatment process that leaves it with a Gummy Matt Finish. The feel is of a rubberized alligator but this is 100% genuine alligator."
