This is a great find! This is the Military Field Gun and it is a rare MB Casting. Released 40+ years ago, this is one of the least produced castings in MB history, with only two variations created. This is variation #2 which was released in 1978.

This is a true cross-collectible, so if you collect Military Vehicles or Matchbox this will be a very nice addition to your collection. (1:64 Scale)
