Anyone know of this Maker?

[STUG III]

A buddy saw it for sale on a site, M43, and wanted to know if it's a legit Maker, I said, "How the He..do I know!". So I ask you, any thoughts, looks like Prosnitz at the end of the name. Thank you all the same, maybe more pics later. Dave

I think it is „Adolf Müller Prossnitz“

In 1939 Adolf Müller took over operations of the hat manufacturer „Stern & Lenkawitz“ in Proßnitz (todays Czech Republic).
