I have a 52-53 Gold flash -pluger model & want some info.Did the early models all have the large valanced guards as seen on the later models.The front guard on mine has a ridge down the middle & is a normal size ( Non valanced ) whereas the rear is a flat guard with no ridge down the middle but a hinge rear portion for rear wheel removal even though it has the Crinkly QD hub.I think maybe the rear is orig but the front is off something else?? Any info appreciated
