I'm looking for a source of new winch pawl springs for some old Merriman Bros. No. 6 winches. These winches are of the type that has a square fitting on the top onto which a ratcheting handle fits to operate it. Each winch has a single pawl and spring. Springs are about 1.25 in long and .25 inches in diameter. I probably could get replacements from McMaster Carr, but that may be a hit or miss ordeal. I'd like to find exact replacements.
