Found the 121 AM Tel & Tel in the same batch of insulators I purchased the 126 Brookfield Creb in last week with the amber stringers. This narrow neck CD 297 with four patent dated and others pending I purchased as an early bird from a lady that was going to have a yard sale this coming weekend. She was selling a group of common insulators at eBay when I noticed her location and emailed her asking if she had any others she would like to sell. She had many more commons which I let her keep and me and just this one took the 30 mile motor cycle ride home.

Both these insulators are in the for sale folder now. Go there for more details if interested. Thanks.
