Hi Scott,
Like Wally, I have a short-decked, open gunwale Morris that's in a fairly inaccessible place (the attached photo is from before the canoe got buried behind other boats and woodworking equipment). I did my best contortionist act to get some measurements for you. The canoe is #15087, so its a little later but still close in time to yours. Its a 16' canoe and in rough condition but never restored or dismantled. What I am calling an "inlet" below refers to the fact that from the the deck edge toward the center of the canoe, the caps are narrower such that the inside edge of the cap no longer meets the inside edge of the inwale (see photo).
To the best of my ability, the caps measure:
Total length: 20"
From point of "inlet" to amidships end: 7"
Max width (alongside the inner edge of the deck): 1"
Width at point where the two caps come together: 3/4"
Width at amidships cap end (before quick taper to point): 11/16"
Thickness: 3/16"
The caps are fastened to the canoe with escutcheon pins at 3.5" intervals. The inside edge of each cap runs slightly over the junction of the deck and inwale so that it hides the junction. You can see in the photo that where the deck ends is where the "inlet" in the cap begins. The cap covers the space between inwale and outwale along its full length.
It will be good to compare these measurements with Wally's.
Hope this helps,
Michael
