Thanks to all for your replies!
The glass was blown inside the metal (I believe it's iron),
The bottle is approximately 'Fifth' size , the glasses about 2-1/2 oz,
Unfortunately, no markings, just pontil scars.
photos posted are: #1 Bottle & Stopper, #2 bottom of bottle, #3 shot glasses, #4 bottom of shotglass.
The set was rescued from a building on Nassau Lane in old town KW during a renovation I did in 2006.
The house had been uninhabited for many years, (except for rodents).
No info was available from owner about the items, or previous occupants.
I was told that in the era it was built, most of the housebuilders were also shipwrights
and used the same construction methods, amazing that with the storms & insects, that this building has survived, it is built with 'Dade County Pine', and in a rather low area,
set on limestone or coral pilings. originally there were several almost identical houses constructed to house cigar rollers, the leaves were cured & stored in the attic.
She had purchased the building in the '70s, and it had remained derelict & literally full to the ceilings with boxes & mounds of debris, just a pathway between the front and only door, to the kitchen area. A hinged bookcase concealed the entry to the attic, stairs rotted, first explored by ladder.
I sifted a few items from the rubble, below are photos of what I believe is brass & iron cabin hardware from a ship, (the old KW residents were notorious 'Wreckers'). possibly the same era as bottle?, a brassbound mother of pearl inlaid cross, in box penciled 'Italy 1949, over 200 years old',
and 2 matchbox size 'Bible boxes' (no idea what they were for), & a limestone gargoyle.
Again, thanks To Breezie for the European tip, & all who read & replied.
Good Day, & Great Digs, Herbie.
