H.R. Pfretzschner® Stamp

[GeorgeH]

Odd one. Seller says "A rare and exquisitely crafted 4/4 full-size violin bow from the world-renowned workshop of H.R. Pfretzschner. This distinctive presentation piece features an engraved ferrule commemorating "120 Jahre" (120 Years), celebrating the workshop's founding anniversary (1880–2000)."

I can't find any other bows with a "H.R. Pfretzschner®" brand. Apparently at some point in the 90s there were two H.R. Pfretzschner firms. One in Markneukirchen and one in Bad Endorf, and they seemingly were involved in trademark disputes, but that may or may not be relevant.

I've been unable to find any other examples of this, never heard of it before, and saw no mention of "commemorative bows" on any of the three different Pfretzschner family-related sites I know of.  The eBay seller deals in an eclectic mix of yard sale, estate sale, or thrift-store type merchandise, without any emphasis on violins or violin accessories.

Anybody else on MN ever see one of these?

Isn't the circle with a R registered tradmark pretty much mostly in English speaking countries? I've never seen  it used in German speaking countries.
