Does anyone know the manufacturer of this French tube?  Is it a French R tube?

Dear Peter,

Yes, sure; it's a TM, the equivalent and forerunner of the R tube... See the TM Rmorg page...

Many thanks for your quick response, Christian.  Very helpful.

The owner of the tube is a fellow collector here in Australia.
