Happen to acquire another Brookfield hoop skirt with the shop number embossed below the ( F- Skirt ) embossing. Seems that this shop number " 3 " and the other CD 152 Brookfield that I posted a few days ago with the shop number " 4 " that also has the upper wire groove lip squared off. No doubt that the mold for these skirt shop numbered pieces was unique from the standard mold for the CD 152 style at Brookfield. This is more than likely old news to the hobby in general, but interesting to me. View " Original " and get a better look at the lip on the upper wire groove.
