I have managed to find a copy of the Production Cats. book in the central library (nice to see an actual pic. of it !) . I think the vase was produced in three (?) different sizes, this one being the middle size,and available in two colours clear and aqua marine (as per this example). Can I just ask for how many years , approx., would this vase have been in production ? I guess as Sweden had remained neutral during WW2 then production wouldn't have been disrupted at all. Cheers, Mike.
