Define this keyway

[jimu57]

I have a few mortise cylinders that have the keyway shown in the photo. The cam on the back has "LORI" on it. The keyway looks like a Schlage 1345 but reversed. Was there or is there a SC1345 reversed? If not, is there someone that can identify this keyway?

Thanks for your help

If it's original Schlage the keyway should be marked on the back of the plug, behind the tailpiece.

I finally found out. It is a Schlage Keyway but has been discontinued. It a reversed 1345. A locksmith in CA has some blanks and sent me a few. The puzzle is solved.
