If there is a patent on them it could be a problem reproducing them. You'd probably have to buy the patent from him.

If there was it's probably abandoned by now and it wouldn't matter if you just changed one thing. You can't patent an "idea".

It does seem like someone could start popping these out as a side line job and make some "extra money" (whatever that is).
