It's an RME-99 "Deluxe" -- c. 1941

As Grant identified it is a RME-99 deluxe.  I have a RME-99 in its typical case along with an early version (note no calibrated band spread dial) of your receiver.

Nice receivers, particularly like the detail on the Deluxe's band spread dial,

What is the long access strip along the bottom of the panel? The deluxe model has it unperforated while the other has it seemingly perforated with hole fillers. Are there coil tuning slugs or caps under it?

Also "BO tone" caught my eye.   Grin. Magnified it on iPad and it sure reads that way.

According to Moore, the strip was put there to allow you to add transmitter or other station control functions to the receiver panel.

Grant is correct, the bottom is basically open in that section.  The chassis is the same as in the smaller size RME-99 cabinet and all of the basic radio is above the "added" portion in the larger cabinet.

Thanks. Neat touch.
One could make up a dupe panel, add all kinds of stuff and save original.
Probably get lost over the years and trades though.

Pedro,

Check to see whether the line bypass capacitors are connected directly to the transformer terminals.  On most RME receivers of this era they are installed there and hidden by a cover, if one fails it will also bake the transformer insulating paper.  I would replace them with modern line rated types AND move them away from the transformer.  Both my RME-99 and the "unknown model in  a case like yours" had the caps installed this way.  I restored a RME-45 for a friend and the transformer in it was blackened because the line bypass caught on fire.

The RME-99 is a nice receiver and I think the last really good RME after the RME-70 and before the RME-4300.  The RME-45 family looks nice but I think they represent a step down in performance from the earlier units.  

I live about 30 miles from the original RME factory site and have acquired quite a few over the years from the RME-9D through the 6900.

Hi Rodger,

Many thanks for the advice, and congratulations on you RME collections, they are very nice radios for shure, Ok, I keep an eye on those bypass capacitors!

Regards!
