A most interesting tube tester, French made in the early - mid 1930's (I suspect). The roll chart features American & European tubes from the early days; (1920's) - to the mid 1930's. The left side of the roll chart shows US tube settings, the right side are the European types.

All original except the meter scale which is my reproduction. I still have the badly warped original if wanted. My replica turned out so well that I doubt anyone would know it's not original.
