The originals were made years ago in the last century.
People still use them with great success at certain times.
Got to thinking......the patent must have expired on these a long time ago.
Even back in the day there were other companies making similar "shovel nose " plugs.......but they are long gone too it seems.
Funny that no one or no other plug company has ever brought one out since to my knowledge.. I'm sure they would sell.
Even a "limited run" commemorative series would probably sell too....
Is it because there's no money in them now to warrant production?........or is there some other reason?
I'm sure Tomic could make them for example........
How long do patents go for?
