and pretty quick i found something interesting at a second hand market.. a big Sandeman bottle, a very big one, a Methuselah. (empty though

all the seller could tell me was that he found it on the attic at his father-in-laws. since the seller looked like he's well in his 60's, maybe 70 and he doesn't recall ever seeing it before they found it i guess it's quite old. so i was wondering if anyone here has ever seen one of these.
there is no label. the glass is very uneven and has air bubbles and other faults in it. the oval emblem on the glass has SANDEMANS PORT written in relief but it's just barely visible and impossible to photograph. no other markings anywhere.
the bottom has a shallow indentation but it is an even depth over most of the surface. quite flat really.
there is a clear vertical line in the glass so it was made in 2 parts at least.
it's 55cm high and 14cm wide.
now i'm doubting if i should cut it. it would make a nice lamp but since there is nothing written on the lower half it would quite a dull looking planter...
