This nice old Hinsdale socket ratchet set, designated No. 10 (for its 10-piece contents?) and B - R, arrived in the mail today. I had previously found 2 Hinsdale S-15 ratchets in flea markets; now I am glad to have the whole set.
I did a little further checking on this set on in Ken Cope's book and DATAMP. The ratchet was patented November 22, 1927; the PAT. number is 1650085.
