Any input on this: Extractor on Ebay

I've corresponded with the guy. The .515 measurement is on there because of my question. The gentleman is a "handgun" Smith doesn't know much about them. He's probably putting "used" because he doesn't know. He also has no packaging telling him part number. Based on the measurement I'm fairly sure they are for std bolt face?

Opinions... Would you buy?
