Details:
The kit represents the standardized M2A1 105mm Howitzer with M2 carriage introduced in 1940 and saw the Howitzer remaining unchanged throughout WWII and beyond. The kit also includes an M2HB cal.50 machine gun mounted on the top recuperator cylinder for sub-calibre training but this was not used once the Howitzers went into action.
The only major upgrades were in the carriages, the initial production guns having the M2 carriage easily distinguished by the smaller single shields (with folding top sections) and civilian-type automotive wheel rims and tires. Refurbished (modernized) M2 carriages were also fitted with combat wheels and tires. The later M2A1 carriage had a double shield arrangement with a smaller front shield and a larger rear shield that extended further out over the wheels with a lower folding flap that provided more protection for the crew.
The other major feature is the use of the standard WWII combat rim and tires. The kit consists of 221 parts in olive drab plastic, 16 etched brass parts, 4 parts in black vinyl, and the full 105mm gun tube in turned aluminum plus the small 10-page instruction booklet.
