Hi Ken,
in case of doubts "is it Moser" is always better than to browse books just directly ask Moser.
www.moser.czTheir support works perfect and they have correct evidence about old pieces as well. Therefore I had put Moser out of my scope - there is nothing to discover, just ask Moser and finito :-)
Here is their direct link:
Can I have my formerly purchased item identified by Moser?
Please send us a product photo and a shot of the company’s logo on the bottom of the product at customerservice [at] moser-glass [dot] com, fax them at +420 353 449 619 or mail them at the address MOSER, a.s., Kpt. Jaroše 46/19, 360 06 Karlovy Vary, Czech Republic.
Let me know their judge than.
Jindrich
