This is a CD 141 - commonly called a straight up - it is a dark aqua with some amber lines/whips from the threaded area down to the base. Condition is very, very near mint with just a couple of teeny pecks, a couple hard to spot tiny stress lines and some minor chipping/roughness at the bottom of the threads. This insulator is as nice as they come.

This insulator would look good at your house!!

Was asking $50 - this piece can be yours for $42 - includes shipping and insurance (in the US...will work with those from Canada). Payment can be made by check, money order or PayPal.
