I own Hull 10 Pearson 323 1977 Chance
Our secondary winches now were our original primaries on the boat.  Back in 1977 they were 2 speed Lewmar 40 winches made in England.  1 Lewmar 8 for the Main, mounted on the mast, and 1 Lewmar 16 for Jib/Genoa, also mounted on the mast.  Both were single speed.  On top of the winches is a round plate that states the size and maker of the winch.  I had covers on my winches for years so I could still read the size and maker information on the round plate.
