Nice job!
I had several of these 'Ever-Ready' bicycle lamps, which I also used as torches, although mine all got chucked out after breaking, failing, etc...
I also recall they were made in black as well as grey.
'Pifco' produced a similarly-syled bicycle lamp, but was chromed with a larger reflector and a slide-switch instead of the sturdy turn-key 'Ever-Ready' version; rather vulgar and brash, in my opinion, as were many 'Pifco' products with respect to 'Ever-Ready'.
The 'Pifco' was 'Empire Made' (i.e: Hong-Kong) whilst the 'Ever-Ready' was a British product.
Thanks for re-kindling old memories!
