    I don't know much but for Combat but for some reason Norton removed the fire starters out from under the ticklers and for a time used the same cases with a stamped steel cover, apparently some time in '72 models they came with the area just cast flat as its surrounds. So maybe some Combats did and some didn't. Then again early Combats earned the Bomb name so who knows what cases were used if the first ones badly injured. Now the area is just for the cute looks of the triangular TS cover and hanging on venting devices.

    Heres a ANTIQUE :p twin , showing all the bits. Obviously it has a HOLE through there ( will see if I can find one ) for it to go through .

    The one fitted forward would appear to be a Electric Starter . :oops: 8)

    Here are a set of cases fitted around the standard hole .

    Alright Matt what is going on with this unique revelation of forward thinking? That drive mount looks cast on.

    That 'drive mount' is the front mounted Lucas generator, fitted to ALL early Dominators 1949 to about 1958 (when Nortons adopted the alternator to the drive side shaft).

    P.S. That front mounted 6v Lucas Generator is driven via a fibre gear and a friction clutch, so tric starting is no-go .....

    Ok thanks Rohan, at least you gave verification that friction drives are good enough for a workable wattage. I didn't think the area was robust enough for starting loads but was wishing it was.

    The blanking plate covered the hole intended for the ill-fated self-destructing electric starter drive that the factory wisely decided not to fit at the last moment for 1971, however the timing side case with the hole covered by the blanking plate continued to be used and it had nothing whatsoever to do with a MAGNETO.

    The blanking plate timing case continued on into 1972, the plate was eventually deleted and the area left cast over once again as it had been in '69-'70 (early 20M3S case).

    Also need that disk grinder and Black & Decker in case of the blanking plate because those fixing holes do not match the magneto holes.
