Hi don't know if any of you guys can assist in identifying my old bike frame. It has been sat in the garage for years and I have stripped it down to resorts. It has no transfers etc but has serial number NA 1970 stamped into bottom bracket and fork stem. It has campagnolo dropouts and rgb stamped in bottom bracket . Any ideas ?? Thanks
pictures are very helpful in these cases, could be a 1970 serial which is my era
