Compression stem for bathroom faucet

[Fred1222]

Trying to find a replacement for this stem. House was built in 1978 and I can't find a manufacturer's logo, etc. It has a 12 point broach, but I have no way of measuring its width. The entire stem appears to be about one and three-quarters inches long. I tried replacing it with a Pfister 910-392 and everything seemed to match except the threads on my old stem are narrower than on the Pfister. Any suggestions?

You probably ought to repost with a ruler next to the cartridge. The trim and other pieces help when people are trying to identify faucet parts.

If there isn't a screw on the bottom, just a hole (I can't tell in picture) it may be a Price Pfister Hydroseal.

I just attached a new picture with the screw in the bottom and a ruler. I'll check out the Hydroseal. My old one looks EXACTLY like Pfister's 910-392 except for the threads.
