I think so too Stefano!
The MAF was ordered by the WO to be brought up to a more WD spec. With built in bash plate, panniers, pillion, air filter and blackout lights. I already have one of these Miller fag end rear lamps in readiness. (Very rare! They were only ever fitted to Fleas, MAF's and a few Miller equipped Matchless G3L's).
Less than a 1000 MAF's were produced, before the WO cancelled all orders with Velocette and put them onto other war work. I guess Velo's were slow to produce, being more hand built, and there was a need for more front line machines that were familiar to mechanics and with a good spares back up.
