Hi Martin I'm new here. I'm rebuilding a 67in Magister and I'm not sure whether it's as yours -Denis Bryant or Dave Platt design. I hope by now you've had a satisfactory reply to your Cof G conundrum and that all has been well with that. When I have confirmation of my Magisters Plan origins I will obtain a plan as I'm going to need one-that's for sure! It'd be good to learn how you've got on.
