Bob, Just a quick comparison. I think this is how it matches up. Still the metal seems light to me, but the shapes all match. I think the sheet metal is the axle band--if you look, you can see it is rounded somewhat that would match the rounding of the axle. As you can see, it goes on the bottom of the axle. I did these really quick, so they are not website quality, but they will get you the idea. Paul More information Ed. Note: These carriage plans are for the M1828 French Mountain Howitzer. The US M1835 was a copy of the French carriage, which went through a number of modifications before being standardized in 1848 following the Mexican War. There are other differences, because the US copy of the French Tube, as cast by Cyrus Alger in Boston, had the trunnions placed on axis with the bore, rather than under axis on the French tube. Bob's attempt at tire diameter measurement from Herb's photograph taken at the Ranger Station in Bridgeport. Herb measured the glassed opening in the display case at 36.5" by 36.5". Using Adobe Photoshop®, the corners of that image of the opening were dragged onto a grid to remove vertical and horizontal camera distortion. From a number of index points placed on the edge of foremost tire rim, a number of digital measurements were made through the center of a circular overlay. The tires are not quite round--a mean was taken. Above right, the trunnion plate (2X) is rotated to its correct upright position. home page Bob Graham
