I bought this last year and finally got around to taking some pics. If anyone can tell me more about it I would be grateful. Height 57cm/22.5 inches and open end 155mm/6". Base says it was made by Patronenfabrik in Karlsruhe in I assume 1900. It sits behind the cats little box, so has collected a little dust in the engraving, but apart from dusting it I am loth to spoil the patina by scrubbing it.
