Brian, you're right about interesting subjects! To this day, only ITC has ever kitted a Pegaso,Talbot, Ferrari Barchetta and Mercedes "180" (I still say it's a 300). Unfortunately, that series was too toylike, even then, for serious modellers, although I think they were better than nearly all Palmer or Premier kits of the day.
I think the ITC 1/25 Fomoco cars I mentioned previously might be of interest to replica-stock builders (with a lot of work) and especially custom car builders. I just might send that email!
