Hello Max,

Nice find! These are some seriously early tubes. 

I am particularly intrigued by the Le Radion one, as we don't seem to have it listed here on radiomuseum.org.

The only tubular valve by that company that I can find is this one:

Unknown_LeRadion , Tube Unknown_LeRadion; Röhre Unknown_LeRa | Radiomuseum.org

Could you maybe supply us with more detailed pictures of the tube and its label? We might have either a new tube here, or at least a new package. All other documented types are tennis ball-shape.

Yours,

Nikolaus Loewe
