Not sure if this is maybe a foreign made spool. The dimensions are exactly 2.5" diameter and 2.5" tall, which most closely matches a CD 1106 that is only 2-1/8" tall. This one is a green aqua color and has a 1-1/16" diameter pin hole to accept a 1" pin. It is shown next to an aqua CD 1090. I could not find anything close while searching the NIA website of foreign glass. So, anyone recognize this? Thanks!! I had two replies identifying this as a tall CD 1106. Thanks so much! I'll bring it to Springfield and maybe compare it with other CD 1106's. If you have one, please bring it to Springfield if going. Thanks again!
