Topic: Acid Etched Murano Glass - Mandruzatto? Help ID Please

[mikebonne]

Hello all and was wondering if anyone knows the maker of this facetted ashtray ?  It is absolutely beautiful and sparkles like a diamond and it has a 2 line acid etched mark to the base that I have never seen before and so not sure if this is early mandruzzato or someone else?  Thanks for any help.  Markus
