7.62x39 Commercial Headstamps

All, is there an internet source for determining non-military headstamps? I’m not sure how I would plug in a search for this one, for example:

Barnayl machine plant (#17) Russia.

Thank you. Do you know of any online guide to all these new headstamps coming out without numbers, with regards to commercial?

There is no such reference, except for the link that I provided, there is still a replenished topic in Russian:
