You used to be able to get 9260 from Admiral. They sold it as 5160, but only in the round edged 1/4 by 1 inch bar stock. Uncle Al had some thick bar stock back in the day. It was 3/8 and 5/16 by 1.5 inches and IIRC one was 9620. Just can't remember which one. I have a ba of each but the white pen writing has worn off.
