Nice to see you back here Harry. I think Terry is right. Also you can find someone who would like to continue working on them and just give these unfinished kits to him.
Or, at about thirty or forty feet, you can practice your air pistol skills ......... or on a more serious note, build them into a diorama for each one, of a battle-damaged, belly landed aircraft. I can let you have a few photos of Do17s belly landed during the BoB, in England and in France. Gets around the landing gear problem, and part of the Do17 rear canopy can be cut off, where it was jettisoned, and damage added to other parts of the canopy if needed. Better than binning them !
Another Harrison eh? Great nameC'mon Harrison you can do do man...KISS principle mate!
