Aerodyne bumpers

[Bellerophon]

Des, there is a way to salvage your over riders if the outer shell has not
been eaten through that is to have a large deposit of copper say 0.050 thou
deposited on them then have them polished until smooth, then chrome
plated. There was a very good plater near Daventry who did this alas like a lot
of things now has closed down.
Some of the liquid cooled aero engines used in the first world war had
water jackets made by this plating process, it being the only way to fabricate
the jacket around the cylinders.
One last thought, I think our friends in Australia had some made a while
back which were cast in bronze, someone may know if any of these are still
available.
Well, good luck.
Bellerophon
