The U.S.M.C. Cannon Car No. 6651 was faster than a speeding bullet, more powerful...well, you get the idea. Lionel made this car on the scale of a 16 inch Battleship gun! No matter, because kids who were fortunate to receive this car in uncataloged sets got lots of play out of it. It came with a wooden projectile that was 1-7/8" long and 5/16" in diameter and was painted SILVER. The car came with only one shell, but additional shells were available under No. 6651-8 (4 each). These shells have been reproduced.

The car was painted OLIVE DRAB over a RED 6511-2 flat car frame with early AAR trucks and disc couplers and is known to have been included in J.C. Penny Set No. 924-3734A in 1965. This set was headed up by the OLIVE DRAB Santa Fe Alco No. 221. See one of the two Instruction Sheets that were printed for this car. There are no known variations.

Due to the projectiles that were used, this car would not get past the "Child Safety Board" were it manufactured today.
