need help from trw 500 cc expert!!!

[preunit13]

i am in dire need of a triumph  primary cover between the 1940's and the mid fifties. it has to fit alternator style.
i was told a 500 cc flathead twin would work. i heard they were on alot of the military and police bikes.
i'm having a real hard time finding one. as long as it is in working order, i don't care what it looks like.
please tell me someone has one? :-/
