True ,S Burman & sons made the boxes for Norton after 1934,not just the doll head,but the tombstone,and the laydown.All these boxes have many common parts ,and common with the 4 sp SA.......Burmans were rewarded by being double crossed by AMC,back when it was run by Charlie Collier.....even the AMC box was just a copy of the Norton box,with modifications to allow oilseals to be fitted.Nortons owned the design,Burman made the boxes,and AMC owned Norton.
