The one on the left is the newly assigned U-2063A from Czechoslovakia. It was my hot, hot seller at the 2014 Farmington National. Sold 4-5 spooks-- two of them even purchased by Tommy Bolack. The one on the left is missing some T-bar hardware but has the cemented pin.

The one on the right is a slightly different design. Look at the dome profile below the eyes. A fuse wire is enclosed in the porcelain cylinder. This one was sold at the Muncie National.

Looking for a California or Postal beehive (California product) that I need for my collection. See my want list at: [id=451835777] .

Cash to even up all trades. Each trade partner is responsible for his own shipping costs. Both parties must be satisfied with trade before it is considered complete. If a trade cannot be completed, the insulator will be offered for sale to other collectors with priority given to past trading partners. Sales prices will be higher than my trading prices.
