Hi,

Yes Robbe FP-T5/T4 was actually a Futaba but the Swedish importer of Robbe back then, "Essen-Air", insisted Robbe was not a Futaba radio (but everybody knew that was the case). Back then Futaba was considered (at least in Sweden) not a high end radio, it was advertised as one of the most affordable low price radios and I suppose the Swedish importer of Robbe radio did not want to be associated with that (Robbe radios was more expensive then Futaba radios).
In USA MRC had a similar radio (brown vinyl case) that was actually a Futaba in 1970/1971 - it was actually this way some years in beginning 1970th until MRC, Model Rectifier Corporation,had their "own" black radios (at least the TX case was black and seemed to be their own).
