Hi Harry
Sent your photos & questions to others who might have an answer and so far the only reply other than “Neat, don’t know” was from George Kass "Went thru my company listings and only one small possibility. Hammond Brothers, Winchester, England."
One other reply agreed with my impression it might be European - French / Belgium manufactured.
Should I hear more, I’ll will post the reply.
Got an extra???

Ok Pete Thanks!!
