Thanks for the memory flashback!  Bought most of my kits in the 1970's at Rexall, Pic and Save, and Hobby Shack.  Even the small-time Bob and Jinny's ice cream truck used to have small plastic kits then too.  With my weekly allowance I could buy a Astro-Pop ice cream and a P51 or ME109 plastic kit.  Scale of those was probably 1/100, but in the hand with motor sounds provided by me they flew great.  They were good at strafing 1/72 army men like it was cool.  Ah, the miniature forts we built in mom's flower bed...  I'm sure there's some of my soldiers and plastic scale vehicles buried in someone's front yard right now.
