Thank T-mar. I am thinking Schwinn as well as the other bike i bought along with this one from the same people was a Schwinn PDG series from '92. here is the inner fork. It looks like amybe those tapped axel retainer holes may have been there as if you look up from what appear to be the drain holes there is a motled area that could have been the holes and maybe they filled in before painting, etc. I appreciate your comments and help with this.
