ive repaired these with epoxy resin and sanded them to a mirror smooth finish
a coat of black on the freshly repaired end,,good as new,,,,well,,good enough
I don't know if they are same as original or not, but I made the newly epoxyed lever fit that lense
Yep,did the same. The end was 'epoxy-ed' in but you get at least 1 bulb's life out of it. These sort of repairs are quite satisfying when they go right,a whole lot more enjoyable than slapping on a modern repro anyhoo !
