This is a shot of the rear skirt where you can see it isn't that common an insulator afterall. The bottom of the skirt is slumped inward about 1/4" deep on both sides near the mold lines. You can see in my pic where it curves or rolls in. It's more a fold towards the center. Had many, many, many Brookfield 152 hoopskirts but none were like this one. It is the round base variety and that whole base looks like it was formed right when the insulator was molded. How the skirt caved in like it has is beyond me.
