I was digging through some boxes of glass and came upon a piece that is a little strange to me. It is the piece on the left. I believe it to be a CD 133 Brookfield [230] - the embossing matches that entry. However, the skirt seems to be wider at the top (just below the wg) and comes vertically down. Also, the glass has a whittle like appearance. I have it pictured next to a CD 133 ER piece for comparison. Anything rare/uncommon about this piece?
