Mick,
The "mytee" company was not in existence in the 70s.
Now I am not here to start a ruckus because I only see that as a waste of time. However, we all know many many examples of (any) companies taking whatever they can in order to get the attention of their respective audience. Further, many companies will also see it easier to "borrow, copy, or take" from their competion. I am sure many of you in perhaps in a similar or smaller way have had this happen to you too.
That's all that is worth saying because other than making my clarification above regarding the correction of a cross american product name in an effort to help the user acquire the proper result, enough said, don't you think?
Best to all and thanks for asking,
Ed Valentine
