There was a flurry of postings on this last November - here's an update.
The originals on our 1992 Santorin Hull #68 were made by the Italian Company, Bonfiglioli. The complete specification is: VF 44 P1 70 P63 B14 B3.
Bonfiglioli USA is in Hebron, KY and sells through authorized distributors - I used Drivetech Automation, Inc. in Sunrise, FL. The cost was $220.00 US each and I bought two (to replace both the outhaul and the furler.) Shipping($18.40) and Tax ($26.40) additional. Great folks to work with and the parts arrived in three days. Drivetech's phone is: 954-746-9800.
The units arrived unfinished - I used a spray aluminum primer and then gloss enamel finish coats by Rustoleum. Will install back on the boat in Turkey next month and expect another 20 years out of them - may I last as long. Likely will install grease fittings after I get back and go for 30.
