ABOUT 2" LONG(Without barrel length)   1 " WIDE   1" TALL. SOME OF THESE I GOT WITHOUT THE CASES SO I HAVE NO IDEA WHAT TANKS THERE ARE OR EVEN WHAT COUNTRY THEY REPRESENT.  GOT THESE BACK IN THE LATE 1970's, EARLY 80's at a local once a year Flea Market.  Miami Miniatures,Metal Figures and Accessories ,Tipp City,Ohio  .WAS GOING TO FIT THESE WITH MY HO TRAIN SET & SLOT CARS,BUT NEVER GOT THE TIME TO DO A LAYOUT.
