Up until I obtained one of these from a friend last weekend, I had never seen a clearly Pittsburg made example of this style. Then yesterday I turned up another in an antique shop. Both very crude with the MLOD and typical earlier style PHV pinhole impression. Somehow the Pittsburg listing for these got overlooked in the newest guide.... whether that's because of "eh..brown porcelain cable - junk!" type thinking, or are they just uncommon? Either way some pretty cool pieces, super happy to add the style to the collection!
