You have all been extremely helpful and for that my thanks. I have acquired a Schwinn approved black saddle and also black chubby grips, (not sure about the matching of originality but the spirit of the parts are close enough) and they are on their way to me now from eBay. I was more worried about the bike model specific parts, however now that I know there is a ‘Sales’ section I will keep an eye on that and cross my fingers that the fender light and reflector will turn up. Thx for the link to the serial number database it’s going to be very helpful.
