Unknown cartridge?

I found this in one of my cartridge drawers. I probably should know the answer to this, but have forgotten.

Bullet Dia. 10mm
Case length 19 mm
OAL 27mm

No H/S

.44 Henry? You are going to have to give us some dimensions in inches to get it identified for sure because most of us can’t do the conversion very easily.

Vince–Any $2.00 calculator can do the conversions easily. However, I agree that anytime dimensions are given here on the Forum that it would be best to give both metric and inch.

Ron, sitting out here in my garage I don’t have a calculator to hand.My appraisal was more visual based particularly on the style of bullet. Its a very “henry” style. As we know case dimensions can be very misleading from this era.
