I am thinking about offering CDs of 3 view drawings.  possibilities would be - military single engine - military multi engine - civilian single engine - civilian multi engine. 

Would anyone anyone be interested in these?

I'm not sure if this info helps, but the 42 nd street library used to have a real nice collection of old model magazines on micro fitch.

Doesn't copy right have a time limit?

 Tom,

 To me it would totally depend on the quality and accuracy of the drawings. I'm sure you know this Tom, but three view drawings are found in many books and other places, but very few are truly accurate. If what you're thinking of would be as good as Paul Matt or Superscale stuff I'd be very interested. Personally, my interest would be from the mid 30's through WWII etc. I'd kill for a detailed high quality Paul Matt type B-25 Mitchell three view also showing the fuse bulkheads and other details. I've yet to find a really good one.
