hi alastair
we put it down to a dicky magneto on the b bank, apparently it's a common fault for old mags to lose their magnetism once they get hot.
I took the tank to shauns hindles place in October as you know for his show and it's still there. the new mag was fitted just last week but it still had a fault on it according to shaun but he hasn't had time to do a full road test yet so the jury is still out on whether the fault has been rectified.
regardless of what pans out at shauns I plan on bringing it back to Manchester next month and carrying on with the resto, mostly small stowage bins in the turret and hull gunners compartment.
I recently bought a "top cocker" Thompson and 16x20rd mags for fitting on the commanders side and i'm looking forward to seeing it fitted. after that i'll sort the bren stowage, it's nice to be at the stage of the resto where you can put the interesting fiddly bits in :-D
