Ok you got me, where can I get plans for these?
That Musciano "Triple Threat" appeared in the Dec 52 issue of Air Trails. They were drawn up to 3/4" = 1' scale witch was pretty much the standard scale that Walt Musciano published a large number of CL scale designs for a number of years. Air Trails sold the Triple Threat plans as one set. For a number of years, that was the no. 1 selling plans of all time for Air Trails. AMA now sells plans separately for each of those three airplanes. The AMA listings for these designs are:
Spitfire -- AMA Plan # 35468
North American P-51 -- AMA plan #23095
Messerschmitt Bf 109 -- AMA plan # 23059
Air Trails did another "triple threat" several years later which included the Grumman F4F Wildcat, the Hawker Hurricane and the Mitsubishi Zero.
Interesting stuff.
