I have 2 pairs of CRM / Firsat steel wheels, they came from a Bertone. I know CRM used to be an ' official' supplier for these wheels. How about 'Firsat', never heard of these... Does anyone now if these are genuine wheels?
Regarding Fergat, Fersat and CMR wheels, I would like to know if the Fergat wheels with the raised bosses to hold the hub caps on my car, a 1964 Giulia Sprint gt are original? I have seen other cars of the same year with the clips on the wheels and wonder why my car doesn't have them? Was it only certain wheel manufacturers that used a clip attachment to hold the hub cap?. My car is Australian delivered.
In answer to your question regarding wether your wheels are the original or not
The PDF below is from a very early parts catalogue , May 1965.
It shows only the wheels with clips but I do know of two cars six chassis numbers
apart built in September 1965, each with a different style of hubcap mounting. GiuliasprintGTwheels.pdf
Thanks for that Shane, so their is a variation some with some without. I just assumed that the first cars would all be fitted with a clip attachment. Do you know if the clip type wheels are Fergat? or one of the others Fersat - CMR ?
I would guess that Borrani (CMR) had more tooling and expertise in the production of rims since that is where they started and stampings like the web of the wheel were sub'ed out to people like Firsat who had that expertise and tooling.. It's not unusual to see subassemblies/components marked by the source of them in the final product. It would then be up to Borrani to assemble the web and rim and take full responsibility for quality control and it would be easy for them to nail down quality issues if the sub-contractor marked their part of the wheel.... and in many cases there might have been more than one sub. Sometimes these agreements involved non-compete clauses on the final product should the sub think they could build the whole wheel themselves.. a piece of the pie is better than no piece of pie. This is typical in all industry, especially where capital is spread around to these small manufacturers which were and still are the case in Italy. Eventually, these small shops get gobbled up in consolidation and it still continues today.
