Here's two SN 22 CREB beehives that I believe are paired. The one on the right has a lehr kiss with glass missing. The one on the left has a lehr kiss with an extra glob of glass. The glob fits perfectly into the depression in the other piece. Both pieces were found on the same pole and sit together on my shelf. These two have probably never been apart more than a few feet since they were created back in the mid 1880's!
