This nice McLaughlin signal I had a bit of a tiff putting an accurate base ID on, but I was informed by a specialist that it's a rounded smooth base. This base looks quite similar to a CD base, has a small ledge on both sides of the half hemispherical base but it is not a CD base. The colour is a nice strong sagey green with a small grey hint to it and condition is VVNM.Very nice and bit more unusual signal for someone who likes the 164's.The SB and RSB are also the earliest made of the McLaughlin pieces. Displays perfect. First mail to me... $15 + actual shipping.
