Due to conflicting information between spare parts lists and Lucas
catalogue, there is a margin of uncertainty in this list.
Lucas catalogue gives dipper switch as shown on this web page to be used
for the Big4 and 16H between 1937 and 1954. It gives the 2 screw fixed
switch as being used on 16H, Model 18 and Big4 from 1945 to 1954.
Pictorial evidence however shows 1939/1940 military motorcycles using the
screw fixed version dipswitches, before being deleted all together at the
end of 1940 and being replaced by the 4 position headlamp switch RS39.
Original 16H 1 inch handlebars can be found with the screw holes in them,
for the attachment of the switch.
*1 Batteries of 12 Amp hour upto early 1940 but marked 10 Amp hour after
that.
*2
Wiring connector is shown in same Lucas catalogue under given number.
Three wiring connectors were applied on the early bikes. One in the + lead approx one foot
distance from the battery, one approx one foot from the regulator "A"
lead and one in the tail lamp lead for easing the
disconnection of the rear mudguard end piece for better access in case
of removal of the rear wheel. It is not known whether the connector in
the "A" lead was applied on all bikes over time.
*3 DME circular B.125, "Immediate action", 21-7-1941, Provision
for immobilisation, All M/C's, *4 Suppressor not certain if
and when applied, example was found on almost unrestored machine from
March 1939 firmly believed to be left behind in France in 1940.
