Actually, each figure set from Dragon is unique. They are based on Ron Volstad's artwork (which surprised me, as I figured the artwork would come AFTER the figures were produced). As far as
I know, there have not been any "repeats". Each set is designed to be accurate for the subject, even if "obscure". In addition, the faces are pantographed down from 1/16th scale masters by
Mike Good, who is the finest sculptor in the hobby.
The probable reason that there are so few 1/32nd scale styrene figures, is that so few "aircraft" modelers like figures period.
Look at the participants at any big exhibition. The armor, figure, and diorama artists mingle with one another, and there is much
"cross-pollination" of ideas, techniques, and talent. The aircraft modelers seem to cling together, and "only" together. If more aircraft modelers would expand their horizons to include figures, and dioramas; then the demand for figures would rise, and hopefully the market would respond.
There are some exceptions, however. The afore-mentioned Mr. Good has produced EXCELLENT pilot figures in 1/48th scale, marketed by Jaguar (as Good Stuff). These are probably the finest 1/48th scale figures ever produced. Perhaps if enough aircraft modelers responded, Mr. Good might be tempted to do something in 1/32nd scale.
