The only branding I see on these calipers is the word Spitfire on the red washers. They were removed from a late 70's Schwinn World Tourist and look pretty good. They are stamped 730 on the back of the brake arms. The back brake is bottom pull. I'm not sure, but I think they can be changed to top pull. The pads appear lightly used. I am selling them as is with no returns. No international sales, Thank you for looking and please stay safe.
