Stem identification - Laundry Tub

[Dannon]

Hello. Trying to identify this stem from my laundry tub. The spline/broach are stripped, so am looking to order a replacement. House was built in 1958 or so, and I would guess this is original. Couldn't find any identification on the faucets. The house is galvanized pipe, and it would be easier to replace the stem instead of getting a whole new fixture. Use my caliper to get some measurements too. It was easier to read the mm on the caliper than the inch reading.

I believe the broach is 16-point.
47-48 mm long
5 mm i.d. broach
9 mm o.d. broach
15-16 mm o.d. bibb washer
23 mm o.d. bonnet washer
28-29 mm o.d. bonnet

Here are some pics:

The style hasn't been made in decades and it may be impossible to find. Ace Hardware does carry some brass and some will have a book full of pictures. If you have an old fashion hardware store you might get lucky. This style the threads wear out and so does the body of the faucet and a new stem may not fix your problem. Sometimes all you need is a new seat washer and packing material and washer for the compression nut and it'll get you by.
