The pictures show the 3D model in Anim8or;
printed in 1:36 scale;
with other guns printed in 1:96 scale;
part of the drawing from the National Archives the carriage is modeled after.
To figure out rescaling in your slicer; divide 36 (the model is 1:36 scale) by the scale you want; for instance: 36/76 = .474 or 41%; 36/96=.375 or 38%, etc.
