I suspect this is kind of a long shot, but do any of you happen to recognize the font (or one very much like it) on this bird identification ring? It belonged to my parrot who recently passed away and I'd like to use his ID number into a tattoo of some kind to remember him by.

Thanks in advance.

wouldn't be a font, it's a mechanical matrix, but DIN is usually a close choice for this kind of purpose.

I suspected it wasn't an actual font, but I didn't know what else to call it. This will probably suit my needs though, thank you.
