Here is a photo gallery of the M56 Scorpion that is on display at the VFW Hall in Marcellus Michigan. These photos were taken in mid 2013. The M56 was produced in relatively small numbers in the 1950s for use by US airborne forces. It saw limited use during the Vietnam war. Despite having not been produced in great numbers, quite a few M56 vehicles survive as static displays. The M56 Wikipedia page lists sixteen Scorpions on display, although the list does not include the Marcellus vehicle.
