The original ones used a harder alloy than the repros - which are much more
easily dented.
The oddball ones are my MGA Twincam, which have a different angle on the
mating surface than anything else.
AFAIK the AC stuff was conventional - had the same angle (I know this as I
am running some Cobra wires from Dayton on one of my cars, but the details of
the ears could have been a bit different. Is it something you could reprofile
on the repros and then rechrome?
Nice you have the wires - everyone seems to want to go with Halibrands.
As for the magnet test, that does not indicate any iron content. In fact
bronze (normally a copper/zinc alloy, the same as brass, can also use nickel
and
cobalt, both of which are ferromagnetic and will give you a bit of attraction
from a magnet. Of course some bronzes also have some iron, so you never
know.
So I think that profile, rather than material is your big issue, although it
is possible, even probable, that the repro spinners you have may be brass
(but a softer alloy than the original bronze or brass)
