Used to fly a JP and I had a Mk4L I purchased new from Mart Aviation but dont know if they are still in business.
Most of the guys in the group had a mix of Mk3's, Alpha's and some US stuff I seem to recall.
Regardless of being mocked, I would wear it in my Cassutt if I could fit in with it on as thats the one aircraft I never want to have a forced landing in....
