Hello PeterS, You can too buy a Monobloc from Burlen's, the one with the hard chromed slide. I have one on my BSA A10, and after more than 15000 km, it looks like new. Accessoirely, for me the sole advantage of MK1 Concentric is its price, but is out of place on a G model. The Monobloc is a much better option, especially with the chromed slide...
Hope it wll help you
