I think what Hector means is there are lot's of donor kit's eg Linberg etc which have never appeared over here in significant quantities (large bandai tanks......) either new or on the second hand market so we rely on certain well known inter web auction sites...
Hi Steve, you are correct.
As for posting a pic of the Fujimi F-15. This kit has long been known as the donar kit for this ship and Shuttle canaris.
Waste £90+ on Three Revell 1/32nd F-15's if you want. I don't need to justify myself.
