Correct Steve, below is some info Robin from The MKM site had provided when I still owned the bike. If only it was a 59cm it would still be with me.
"The frame looks absolutely correct and the head badge was one which ran for a short while when they first set up. The original plan was, possibly, for Ron Kitching to provide some finance to the company but he was very concerned about the business skills of Arthur and Wes and so limited his involvement to buying the Chapel Works and renting it to MKM.
This so upset Arthur and Wes that they changed the MKM to MM, they planned to change the company name but this proved to costly and so it stayed as MKM.
Congratulations on finding an MKM frame in original condition.
All the best
Robin Hatherell"
