What does the dial say. ?  Stations or wavelength ?- That often gives a clue about date and country of origin.
Is there a wave-band change switch?
The two symetrical pins are the heater; that spaced out on its own should be the anode.. Heater could be 2v or 4v.
Do any of the valve holders have an associated flying lead which would reach a top-cap or side-terminal on the base?
Are there two lots of leads for batteries?
 or a mains lead?. If a mains lead then one of the 'valves'  was a barretter (voltage dropper )
Loudspeaker or headphones?
 
It is of course a TRF Rx. . Does the tuning condenser have one or two sections? If two then one of the valves was RF amp. Daintily wipe away gunge on chassis you may find valve type numbers printed under gunge.
It is not 100 years old...valves not available then.

Subject: LF: PORTADYNE

Hi All
Has anyone ever heard of a vintage radio called a PORTADYNE. Radio maybe 90 - 100 years old. It has 4 valves, which are missing. Unusual valve bases 4 pin with one pin offset, bases look small. It has a loop antenna wound around the inside of the cabinet. It has a rotary base plate to swivel the radio for best reception. The case is the usual polished wood.
Any help appreciated for restoration work, cct etc or original box !!
