Classic Wire Terminals

Dear Sir,
I am restoring a 60 ft 1924 Nicholson ketch in Australia. We have cast new chainplates and have new bronze Stalok turnbuckles and toggles. I plan 316 1x19 s/s wire rigging with sizes ranging between 10 mm (3/8 inch) and 22mm (7/8 inch). My query relates to the wire terminal. I would prefer some form of bronze fitting.

I have seen a bronze terminal in which the ends of wire are spread and bent over, and then the ferule is filled with lead or epoxy. Does anyone know who supplies such fittings, and how reliable they are?

Any other bronze ideas?
Steve
