I'm not sure whether some of the plugs I have are stickly for radios but I have a number of original bakelite plugs which had been kept by my father and date back as far as the 1930's - he was an electrical supply salesman and an electrican and beleived you could never have enough spare bits! If you would care to keep an eye on e-bay, I will be putting some of them up for sale within a week or so. Hope you find something to your liking.
