AHT describes the -1C as a -1'A' with 4x20mm cannons. It had the -1'A's leading edge fuel tanks, giving a total internal fuel capacity of 361 gallons v 237 for the -1D. It also lists the max external fuel for the -1C as 175 gal, v 300 for the -1D, which also points to 1 hardpoint.
I also have another book which is not nearly as thorough as AHT which describes the -1D as the 1st to have the twin pylons.
I am thinking that modeling the -1C as a cannon armed -1D was incorrect, it should be a cannon armed -1'A'. This is not a big deal, but it would be nice to have the historical accurracy. It would also be nice to have -1'A's modeled, a lot more of them were produced than the -1C's.
