Opening this up a bit, now interested in any primary between 6 and 12" and f3.8 to f4.5. Still prefer conical but standard considered at the right price.
Edit: Thanks for the PM's.
I should have been clearer, for the larger diameter primaries I would be looking for the shorter f-ratio's.
So, any diameter between 6 and 12" at ~f3.8,
8 to 10" at f3.8 or f4,
6" from f3.8 to f4.5
Cheers!
