Found this vintage Hoppe Super 1/2" Drive socket set and case recently.
Good score for under $4 CAD.
The ratchet doesn't work, but most of the sockets and extensions
look good.
The majority of sockets are Hoppe brand, 2 Challenger (Canada),
the shorter
adapter is made by Armstrong (USA), and one Taiwan socket.
The 7/16 socket must have had a special purpose based on all the
grinding marks to reduce wall size.
