Hello,
I'm new here, so if I'm in the wrong area, please... be gentle...

I have an old and very beautiful bottle (wine/alcohol?) which states "Made in Italy" and has what appears to be a crown sitting atop a heart shaped symbol or shield, as the makers mark. I have spent a dozen hours (off and on) looking for this over the last couple years, but have never found a very detailed "Made in Italy" bottle glass information source.
For reference, I have included a few pictures of the Cathedral styled bottle, along with shots of the maker's mark and "Made in Italy" stamp.
Any assistance with direction towards additional information or identification would be greatly appreciated.
