From my personal collection to yours! This is one of a pair that came out of a Southern California bottle collector's collection. A good strong purple, one-piece California transposition, CD 200. Has only an open bubble on the base (side) with an associated sliver on the inside base. There are a couple of wire rubs in the lower wire groove and the typical California stress fractures, including a narrow one that runs from the upper wire groove to just before the top of the dome. About a mile's worth of dome glass to boot. What California glass collecting is all about. Asking $1,600 and I pick up the shipping and insurance. See the second photo for a close-up of the base bubble [id=97813238]
