Adaptor Index
This index is a quick way to find the socket ratchet adaptors
This is for the early (1931 – 1958) adaptors. It shows the odd ball socket sizes and the adaptor numbers for these sizes. These socket sets are obscure and really unknown today. There are about 30 adaptors here (31 actually) of which 2/3 (19 actually) involve sizes not seen in modern tools.
