This is a model of the P1 pontoon in use since WW II by the US military. This barge is 3x13+P3+P4 modules using the P1, P2, P3, and P4 modules. Used by the US military in amphibious operations. The model is 2 pieces first the top deck down to the waterline the second the waterline down. This allows for it to be used in a model as deployed in the water or if glued together as a barge sitting on land or a ship’s deck waiting to be deployed. The dimensions were taken from manuals and then adjusted to meet the limitations of printing at this small scale.
