German Gas Mask Markings? H.A.G. III?

Does anyone know what this mark is on the inside of this gas mask?

Would like to see a little more of the mask--like the markings on the metal ring at the chin. Thanks.

I have a few masks with ink stamps similar to this one, although they're not as clearly defined, and I have yet to find any information on what it means. It looks similar to the Bekleidungsamt (B.A.) stamp but I'm not sure if it's a distribution stamp, quality control or something else entirely. Not all masks that I've seen have them. I will dig some of mine out and have a closer look.

The H3 stamp embossed into the metal face plate is the maker and size, 3 being the smallest.

The filter has the maker stamp AGFA, the date, the filter type 11-C-11. The red stamp I believe is quality control.

Thanks for the input! I've been searching and searching trying to find a stamp like it or what it means, but to no avail.

Looks like a very nice example.

I just realized that your mask's filter plate doesn't look to have a red number ink stamped onto it. I assume these are some sort of quality control stamps. I know most if not all of my GM17 masks have this sort of stamp on the filter plate.

I'll have a closer look to see if my H.A.G. stamped masks have the red numbers.

Here are two examples with the red numbers I'm referring to.
