Karl [Jager] made a suggestion when we were working on an aircraft card, as there were too many options for a single card for some planes.

However, there are a few planes, especially German, where there were factory or field kits installed in planes, that really didn't change everything on a specific type. Take the Bf.109E for example. The E-4, E-4/N, E-7, E-7/N, E-7/U2 had basically the same stats, just different options. The E-4/N could carry bombs, the E-7/N could carry bombs or drop tanks, and the E-7/U2 was a Ground Attack variant with extra armour and a bigger engine to compensate for the weight (So, perhaps a bigger damage rating on this one). FW.190s have an even bigger spread of variations, with small options within each variant, in some cases having huge difference in WoG game terms.

The advantage of this is that we don't need separate cards for each variant, just an equipment card. I have started this process with some cards here: OldGuy59's WGS Equipment Cards Album

A quick look through the unofficial stats will show how this could save a lot of card production: Thread - WGS Unofficial aircraft list Version 1.0

It could allow players the option of fielding equipment or variants in scenarios without new models, as well. It may not appeal to those who demand WYSIWYG (What You See Is What You Get).
