I would like to preface this by saying I'm quite familiar with size variations among CD #s but this has me stumped. So I'm searching through this horde of insulators 4 my friend and I come across the Brookfield signal. At first I thought it was a 134 but it has an inner skirt. Upon further inspection it does not measure out to any CD number in the book. It's way smaller than a 162 the closest thing that resembles is a 161.2 but it doesn't match any ein number in the guide It is 3 3/4 in tall and 2 7/8 in wide in ice aqua. Fskirt BROOKFIELD Rskirt NEW YORK. Any thoughts. I can provide more pics. Please help.
