With side decals thought to have originated some time around 1957, with the oral history of the boat its before 1960. In any event, it takes special skill to get the same angle on both sides
yup, canvas rotted at the top and rather than redo it they refastened and made those goofy big rails. Oh, the ubiquitous drywall screw was used with abandon...
The Chestnut catalogs show a number of different side decals and alignments during this period. The 1956 catalog had two at different angles and one straight while the 1959 had actual nuts like the nameplate as shown below. Nice find,
