These are most of my finds from the big hunt last week with Mike Spadafora, Tracy Schaff & Reed Thorne. The left one is an original M-3471 Thomas. It is also sitting in Mike and Tracys hotel room here: [id=328742637]. The top has ThomasD S, the middle ThomasD O and the bottom just and O. The middle multipart is a Victor M-4140 and (judging by the pin compared to the others) may have been an early replacement for the gray OB or M-3471. The top has the Victor multipart logo. This is one of three M-4140 known in the hobby today. The last multipart is an OB that is very common in SC.
