Yes that's the point. As far as I'm aware, prior to Campag Record brakes in the late sixties, most brakesets had a longer reach brake at the rear, and most road going frames would have been built to accommodate it. A road/path frame would usually have been expected to be able to accommodate mudguards too. Your frame has the mudguard eyes, but lacks the bridge/crown clearances you'd expect to accompany them, so it could be either a road geometry/clearances ten+ years ahead of its time, or a track frame modified for road use ten+ years after it was first built.
