I was contacted recently by a prior insulator connection, and this is part of what came of it. It's a CD 145.6 EIN [010] (Base of inner skirt) BOSTON BOTTLE WORKS/PATENT APPLIED FOR {Four segmented threads} {MLOD} SB in Blue with a few bubbles and lots of milky worms crawling all around as shown in the baselit photos. [id=498623262] Condition is quite minty with only two tiny base edge slivers. Way better than any others I've seen. Inquiries welcome.
