Old French "HWB" with 16cts and hornstem

[capitano]

Hello smoking community
time ago I bought a "HWB"- pipe with 16cts gold-sleeve and hornstem in southern france - see pics.
Very dirty and extremly well smoked, but looking like a 1900-1940 pipe with potential.
Does anybody know little bit about the pipemaker/ manufacturer ?
Only "rebornpipes" deliver a little story but nothing essential about "HWB".
I believe it was a little factory in the area of St.Claude .......
Infos very welcome.
Thanks
Good smoke - Torsten

Reminds me of Ropp pipes. No idea if related tho!
