It's a No.44! Thank you!
It can be used as a hermaphrodite caliper simply by inverting only one leg, so you get one "divider" leg and one outside caliper leg.
I rarely use it because I've got a DRO on my lathe, but still handy to have and I'd never give it up. I don't know when they discontinued it, but I've never seen another.
P.S. - I measured mine, it's the smaller 6" version.
