I have a Plath bronze manual windlass (similar to the ABI windlass) for sale in Olympia, WA.
It comes with the hawsepipe and cover.
It is a very reliable double action windlass that does not rely on electricity and needs almost no maintenance.
Asking $500, but you will need to pick it up in Olympia as it is quite heavy.
You can find the specs on the website for RC PLATH, www.rcplathcompany.com...it is the model 7 with the rope gypsy and a wildcat that fits 5/16" BBB chain.
For an extra $100, I will sell 120 feet of that chain with the windlass.
I do not have the handle, but the handle is easy to fabricate and I suggest you do so so that you can make a stainless one that is longer than the standard handle (which is steel).
This photo is from the RC PLATH website, but mine has been used for 4 years, and has a nice green patina all over it now.
It works very reliably and easily.
