I picked this oldie up from a taxidermist in Illinois. It is in need of a redo for sure. The serial# is B97688, but I get different years of manufacture depending on the resource that I use. It seems to be either 52, 54, or 57. The exact age is not that big an issue, but I was hoping somebody out there might know the model name.
I plan to have the frame, fenders, and chainguard sandblasted before repainting in a similar color scheme.
Does the chainguard design offer any clues to the model?
Is the scroll decal any help?
