I just got an erie 71 and it has front ad glass holder instead of the scalloped design that is usually above the face plate, It is marked 71 yet in the gas pump book it only shows a model 91g and 90 having the ad glass attachment on front, was wondering if this is a rare model and if anyone knows about it, Ad glass holder is obviously original as it has the scalloped design on top and bottom of ad glass holder
