Here are the three CREB 145s that I found on my 3-14 hunt. The other insulators are still soaking in the acid.

On the left is a no SN CREB with horizontal patent dates and the 45 Cliff address, in the center is the FAB error CREB and on the right is a 16/upside down 16 SN 45 Cliff St.

Still haven't found an 1870 or Fulton St. piece. Sooner or later...
