Series 3 rear hub - production change date?

Does anyone know when in Series 3 production the rear hubs changed to the SX/GP type?

The front (drum) hub design changed dramatically in January 1964 (according to Vittorio), but I've never been able find info on when the rear hub was changed. I always assumed it was around the same time, but I was recently given a Golden Special project (July 1965) by a good friend, and the rear hub (in original paint) is the earlier type. Any ideas when the production change was made? Late '65? Early in '66? Even later?

OK, let me rephrase the question. What rear hubs do people have on their original paint late 150 Specials, late TV175/200 and early SX200s? Early or late type?

According to Giancarlo at Tutto Lambretta, the production change to the SX/GP hub (part #19545120) occurred in late '65.
