I've had these a while but not got around to posting them... and as someone suggested having a mystery object to test your grey cells against, how about these for starters?
They are quite small - only a couple of inches tall, but the metal part is around 4-5 inches. Inside them you might be able to see a tube going down from the lid, and each of them came with a spare tube - you can see them laid across the bottom inside each glass part.
Any suggestions as to
1. what they were used for
2. maker
3. age
:rn:
(I should say they are marked on a part you can't see on the photos so I do know what they are. I'll reveal all in a couple of days if no-one gets it right.)
