Does any one owns tube portable radios that have F.M.?

I own Austrias first all tube FM portable radio:

and its hybrid successor

This radio offers not only a built in mains transformer but also a transistorized DC/DC converter which obivated the anode battery

1st times I've read Australia and I wondered how come portable tube radios with F.M. in 1957 since in Australia F.M. camed only in 1975.
But it was Austria. The radio had 5 or 6 tubes for radio frequency as I can see. Most had only 4. How did it worked on radio? And what F.M. frequency range it had?

I finished the restoration of the hybrid set 2 weeks ago. It's now possible to directly compare the tube version with the hybrid.
Both sets work surprisingly good, espcially the sound quality of the tube set is impressive, even though the output tube is not really strong to save battery capacity.
To the restoration: Both sets usually have massive problems with a built in rechargable battery which leaks out it's acid that causes a lot of corrosion usually. Also the handle is usually broken as well as the antenna.
Finding a good example can be time consuming and expensive too also these radios are quite wanted and sell fast usually.
