I think your lamp was made in March 1963 - a real vintage Wink

Wow that's pretty old, thanks for the lamp as well as dating it! I saw a Tungsram HgLi 250w on LG made in '77, they must have been the very last in Europe to use this shape!

There was only a handful of European manufacturers to produce this kind of shape, and Tungsram was indeed the last to market it. I guess this must have been a common practice in the Soviet era to keep production tools and methods for as long as possible.
