RC was not 100 years ago ;-)
F1 Freeflight gliders and rubber motors were the thing and still are for those skilled people who really can build, trim and fly models. Some time later came the gas engines, then diesels an glow if I am right, but still without RC.
F2 Line Control was ruling when the IC engines became more available.
F3 Radio Control was very interesting with only one channel for rudder and a really big ground station with a tube as amplifier. The transistor was not invented until 1947 and equipment with transistors was not common until beginning of the sixties.
You will find special clubs for vintage flying models.
SAM is the natural name in the US

SAM is Society of Antique Modelers - i wonder if it is correct, is it Modelers or Models, or is it the same?
Most people active in the antique model flying are "seniors".
There was no need for HobbyKing back then as there was lots of model flying clubs normally had most needed materials in stock. Most countries had some model factories making kits of popular models.
Yes Nightflyer has a lot of RC history in his "shed".
