Well it's technically a Westy blackender (since it's a few years after the Philips buyout) and ACE bulbs were really made by Philips before they switched to GE.
I've still never seen a T8 blackender before, and certainly never an ACE one!
i remember a clear 150w norelco bulb for sale at an ace hardware store in watsonville, ca as a kid. it had a single coil C-9 filament! also the ace hardware brand bulbs in around '86 were made at the norelco plant in lynn, ma the incs and all.

The T12s had Philips endcaps but the T8s had older GE type endcaps.
At least the ACE where I lived.
