FRANCIS TWIN VERTICAL WINDLASS ON 1984 BREWER #10

My Brewer is fitted with a FRANCIS 1500 twin vertical Windlass. One drum for line and the second for chain. it is a great windlass and right now works just fine although a little noisy.
Does anyone know where I can find out more about this Windlass and is it still made by anyone? I am looking for a parts source and shop manual if I can get them.

The Francis 1500v, on my 1984 Brewer was made by HAMBLE CRAFT who also made horizontal windlasses and capstans. I have the install instructions, specs, wiring diagrams and gearbox drawings if anybody needs them.I have not tried too hard to contact them, they have a postal address but no internet presence.that I can find.
