This item is a plastic military vehicle model. It does not require either cement or paint to complete or use.
The incredibly massive German Dora rail gun of WWII featured a huge 80cm cannon, but was only used for a total of 13 days, with only 48 shells being fired. It took 25 trainloads of equipment, 2,000 men, and six weeks to assemble the monstrous gun at the firing location.
Previously offered as a plastic assembly kit, this Dora is now available from Fujimi as a fully assembled and expertly painted display model, complete with base and clear acrylic case. The detail is amazing, the finish is astounding, and the size is impressive!
