What year are these clubs from?

I have a set of Macgregor Tourney irons that I have no information about. I have done lots of google searches and can't find a single thing on these irons. If you want to see what the iron looks like go to

The picture shows a 9 iron. Marking as you can see is R9MT. I have that one as well.





Please any information would be awesome!|||Looks like 1967 from the website you listed.
