This endcap is from the genuine Lucas authentic classic range - and is the screw on aluminium end cap with black centre type (with cutout pickup), as fitted to original Lucas K2F magneto's - but was also found fitted to some single cylinder mags.
It is listed as original part number - 459269
As you would expect from the genuine Lucas range - these end caps look beautifully manufactured and are constructed as the original items were - with an aluminium knurled constrction, but with a black (plastic type material) centre.
I can see that the cap is assembled with a breathable space and includes a central wire pickup assembly - allowing for a magneto cutout button on the handlebar - and also includes a graphite pickup and spring in a seperate bag - That fits into the central hole on the inner cap assembly. This mechanism allows the graphite pickup to gently press against the central points plate bolt of your magneto - and when the wire is attached to a cutout button on the handlebar, will allow the magneto to 'Earth' and provide an engine cutout when the button is pressed.
Also on the inner cap is a rubber O - ring seal, to protect against excessive condensation.
As an FYI - although this endcap is listed as being for the Lucas K2F (standard roadgoing twin cylinder magneto - as fitted to many parrallel twins, including Dominators) - In period this type of cap would also be fitted to numerous single cylinder magneto's having the same 'screw-on' threaded points end casting - i.e. the Lucas Lucas NR1 and Wader magneto's or similar. This black centred version was more commonly fitted to non-competition magneto's - but the fitting is the same as the genuine competition type version that we also sell (Item 1189) - so if you prefer, this type could be fitted to a comp magneto as well, I have seen many restored comp mags with this type of cap fitted, and they are slightly cheaper.

Overall, these caps look beautifully made, and being made by Lucas themselves, are a welcome addition to the Classic range - as they were previously a rare item to find in good condition - normally the knurl is mauled and the black centre section sometimes broken.
