How do you know that the etch is inside the lamp? I thought only the Americans and the Japanese ever made lamps with inside etch.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

Yep, it is inside etch. You can see the outline of the absence phosphor coating where the ink was imprinted inside the tube.

Pretty, please no more Chinese failure.

Nice find! It is possible that this tube was made in January 1955 according the date code RPa. The only thing I don’t know is what the R as factory code means?
