Blackout Lighting + filters ON guards

[sth65pac]

Has anyone made the small blackout lighting parts (for the guards.) or filters etc. I have two bent and two damaged examples.

Any ideas would be welcome.

It looks to me as if the prototypes were made of Brass Hex stock and then turned up on a lathe, and then cast in mass production in diecast (*whitemetal). If anyone has made repros, or has some extras lying around let me know.

It is great that the thread is so fine that they dont seize, 60 years on..

I have two square backed examples.. (Ford?) and two Acorn (Chev?) All with dented fronts....Help on ideas to make them look nice.
