That is a gorgeous bike! Do you know anything about the rear tire? I searched the web and other than the catalog, your bike (and mine) are the only ones coming up with the SLIK tire outlined in white.
Let me share a picture of my twin to yours - also a very recent find from an estate sale. Mine is a December '65 and I'm thinking it came with the '66 style sissy bar. It is seemingly all original and cleaned up very nicely. The rear SLIK tire and front Westwind are excellent as is the smoothie seat. Some serious rust was on the rims, but after a couple treatments of Naval Jelly, 0000 steel wool and some chrome polish, they look great.
