If additional coil sales would reduce startup costs, I suggest you 
also look into manufacturing National SW-3 coil forms.  The SW-3 was 
a regenerative receiver sold in the early 30's, and is currently a 
very desirable item.  It uses a 6-pin coil form with normal pin 
diameters, but with different pin spacing (since the receiver was 
designed and originally sold before 6-pin tubes were available).  If 
you are interested, I'll provide details.
