Hey, Ed, It's nice to finally meet the man who found my bike!
Actually, the bike you are calling a B-6 is actually an early 1950's Green Phantom with wrong parts on it that I painted up to match the frame of the Phantom, instead of chrome plated fenders. The fenders that are on that bike I installed on it in around late 1974 hame from a girl's Hornet ballooon tire bike that I bought from Harvey Williams Schwinn for $15.00 for those fenders. If I am correct, the front fender should still have an original delta script fender mounted torpedo style headlight on it with an offwhite paint on it. One of the things I marveled about that light is that it never had batteries in it until I got it in '74, and the original instruction card for working the light was still inside the unit. The rear rack I put on the bike, I believe came from a mid 1950's JC Higgins that I painted with Pactra Leaf Green to also match the green frame of the Phantom.Here is the best picture I have of that bike. It was taken in 1976, 6 years before I sold it to Martins' Schwinn (That is what the business was called when I sold it and my Panther to them in 1982), now Martin's Bike Shop. If this is the bike you have or know its whereabouts, and it still looks like this, I might be interested in getting this back, as well.
Edit; just one other observation to what you said, here, I still own my 5 speed Corvette, as I never sold that bike to Martins. As of the upcoming year 2020, I will have owned this Corvette 45 years , come this May.
Jim.
