Looking for a diagonal mirror for my latest ATM project.

Preferred size is 70mm minor axis (2.75 ") but there's a little wiggle room on the exact size.

Known quality (maker or flatness test result) would be appreciated.

A secondary holder would be helpful though not essential and I'd be happy to consider a package with a holder and spider.
