Photo of two neat 'beehives'. The one on the right is a normal U-228A. The mystery item on the left is of an unknown U number to me. It is a giant: just over 4 1/2" tall, and a base of 3 1/4". I have owned this one for many years. One prior owner tagged it as U-149A. That is certainly wrong. If anyone has an idea on what the U number is for this, please let us all know.
