Three out for of these insulators were purchased from a vendor I had picked up a good many from in previous years. Those three were the only Crebs he had this weekend. Two have Jan 22th patent dates. One has no shop numbers and the other a #3 which I didn't have. The other two have a #11 and backwards O6 on the front crowns. Didn't have the 06 in my collection. I had a a backwards #11 but not a correct #11 like this one. The remaing creb has clumps of junk scattered around. Last year I had one with the same kind of crud at the top of dome but this one came from a different vended then the three I first described above. My plan is to keep all of these in my steady growing Creb Beehive Collection.
