Here's another Nifty '50s toy, the Wyandotte MATS Cargo Plane. 'MATS' stands for Military Air Transport Service which was formed in 1948 after the United States Air Force became a separate service. It's predecessor was the U.S. Army Air Forces Air Transport Command. MATS, in turn, became the Military Airlift Command in 1966 and then Mobility Airlift Command in 1992.
I saw a very similar plane in a 1953 Sears Christmas catalog but with different markings and a bomb drop feature. The plane measures 13" (33cm) W x 10" (25.4cm) L x 3" (7.6cm) H. It appears to be C-97 Stratofreighter.

It still has the original price take from F.W. Woolworth's Five-&-Dime store. I can't make out the price but it probably wasn't much!
