Has anyone seen this one before? The back is scraped but enough visible to show it is an early "Lorioli & Castelli… Milano via Anzani" maker’s mark. Also note invisible to the naked eye is what looks like a scratched reference number of sorts on the back along the rim below the pin circle… (see my photos)… looks like 101.H3-24A (or) 101.113-24A

Thanks in advance for your help if you have seen it before or know of this one…
