I have this frame I have being trying to identify for a bit. It is a steel frame. I know it probably isn't anything special, but it was free and I am going to use it as a commuter. There is only one mark on it and it is G100619300. I am thinking about sanding off the paint near the serial to see if there is anything else (Repainting it anyway.)
All it had was two sets of braze-ons for bottle cages, and rear dropouts. However, I just had eyelets and a single boss brazed on. I took off the gray tape.
Image when I first got it. It isn't a great image.
Any ideas? Thanks in advance!
