Through the ag fields, the poles were pulled and glass buried in the holes. These swirly Brookfields have a nice contrast of that late production tealy aqua and rich amber (as opposed to olive swirls). Interesting to note the BFNY made of the same swirly glass in the mix with the plain BF pieces made from very worn molds. I have long suspected that BFNY mold set got set aside for 10 years and was later put back into service. This evidence tends to support that theory.
