Ivo, thank you for your help... I've been looking into Afors, but to be honest, I haven't been able to come up with very much information. (And it doesn't help that when I google 'Afors', the search engine keeps asking me if perhaps I meant 'Afros'...

.) Even the GMB has rather limited information about the glassworks.
May I ask why Afors sprung to mind? Have you seen vases similar to mine that were produced by them? I appreciate your help... and an ever-so-delicate shove in the right direction. :kissy:
