Here's a tough two piece porcelain battery rest with cool criss cross and "X" pattern on both pieces that I've identified on other early Norden insulators from Denmark! Unembossed. Top piece is 3 3/8" wide and bottom piece is 2 1/2" wide. One tiny rim nibble otherwise MINT.

First email gets this tough battery rest for only $100 plus 11 shipping. Thanks!
