Need a raco Key

[GregWhitney]

For future reference here is the dual-purpose key:

Thanks for sharing wylk. I have two different versions in my collection - one like yours with a more "chunky" casting and a hole drilled through the hex socket and another "smother" casting without a hole. The latter also has a much shorter hex socket.

Sadly, neither have a makers mark on them. If anyone has information on RACO vs. SACO vs. ?? please share.
