Just seen this by Endici it is the same badge I have posted.
He is down as an Experienced Seller and is advertised on this forum, he describes the badge as follows.

This is an original NCO's Cap Badge of the Scots Guards. It measures 42mm high by 44mm wide. It is made from bi-metal and is in good condition with holding lugs undamaged and intact.

It also measures the same as mine.

So this after all could be an original badge put together the wrong way around.

Thank you to all who have give there opinions on this matter.

Best Wishes
Paul.
