Help identifying insulating material

Can anyone help identify this insulating material. I always referred to it as fisch paper. I can't seem to find a source anywhere.

The needle nose are underneath to show it is slightly translucent.

Perfectly functional but opaque fishpaper is sold at the NAPA car-parts store as "Gasket Sheet". Bring a sample so the clerk can get a fair match on the thickness. Yes, it comes from the same rolls of vulcanized fiber as fishpaper.

You may find that translucent sheet at a Starter and Alternator Repair shop. Even better, a shop that also rewinds large industrial motors.
