After 1955 Seeburg, AMI, Rock-ola and Rowe / AMI all used tube shields at one time or other but I do not know which sizes fit which specific applications.
Therefore I have sorted and grouped all of my different tube shields according to size and the markings which are on the top end of most of them.
This listing is for a group of two that are either marked TS103U01 or are the same size if not marked.
Many of mine are also marked Cinch, but others are marked Elco, Eby, 139 or are not marked at all.
I will first send out the nicest beginning wth the Cinch. When they are sold I will send whichever I have most of next, and so forth.
By searching for that part number on eBay I see that other sellers indicate that this size is used for the tube types listed below, plus others I am sure:
9 pin miniature such as 5670 or WE396A.
Height is 1.50 inches (3.81 cm).
Diameter at top is 15/16 inch (.9375 inches or 2.38 cm).
