They look like South Coast #5 winches. They have been out of business for quite some time. As to their worth, I have no idea. The wear marks appear to be from the handles rotating across the top of the winch. www.marineconsignmentmain.com has the handles for those winches. The winches themselves look similar to Merriman Bros #5 but the screw placement on the top of the winch is different.
