Greg, I don't think I have ever seen a later (small) voltage regulator painted black. All I have seen are plated. Although it would be easy enough to paint over the plating if you were so inclined.

I have a nos small black regulator in the Porsche box. It is in storage so I cannot give the number. Bosch spec sheet has 0 190 300 055(large) fro 09/59 to 09/62. Then 0 190 309 017(large) to 07/63. The small regulator 0190 350 008 was from 08/63 til... I also have the bracket that adapts the small regulator to the large holes in the firewall. Tom K

Any operational benefit there, Vic? Mine is the black one and car was made in September 64.

No operational benefit to the small silver one. If your car has one, you had better be careful.
Joe Leoni said that if your battery is low and you are driving at night with all lights and wipers on, the current demand will drastically exceed the safe limit of 23 amps, and your generator will smoke itself (throw solder from the armature) by trying to provide it. The small silver regulator will allow some 40 amps to pass through on demand.

Jim Learmonth lost several generators from this effect before he got rid of the small silver regulator on his 65C coupe.

My 65C had this same small silver regulator on it, and I dumped it and replaced with the large black regulator, which I had Joe Leoni set with a 23 amp limit on it.
My 64C coupe came with the big black regulator on it--so no problem.

Chuck - when you say you have the black one - is it the later, smaller style but the cover is black and not silver?

Our 1964 RHD 356C coupe chassis #129856 according to the CofA, left production line 12 June 1964 first registered in UK on 3 September 1964, has the silver regulator and is fitted with plain (non badged) hubcaps which I understand were as used on the 904. (Probably the closest I will get to owning one)

Look closely at Wil's 65 regulator. It has adapter bracket I pictured above. Tom

I finally got off my duff and went to look at my VR. Here's the regulator from my car - original? Who knows, but the black paint is very patina-ed.
I've seen black covers on other cars in the past.

Faithful:
Another minor difference between the '64 and '65 cars is the two hole crankshaft pulley. The factory ran out of 4 hole pulleys in April - May 1964. This was only about half way through the '64 model year. Like everything else about Porsches, nothing is hard and fast, but 4 hole pulleys on '65 model year 356s are pretty rare.

There were only two differences in the 1964 and 1965 cars. The first was the recliners on the seats were smooth on the sides similar to the 911 with the same problems as the 911 of latch failure. I believe the second change was that the cars had 13 and 14MM heads on the bolts and nuts to accommodate these a 13MM combination wrench was in the tool kit.
The electric tachometer was installed in February or March of 1964. al zim

I find myself in disagreement with the idea that a silver voltage regulator was stock on C's. My C cars have had black covers on the VR's AND I check the date codes on them. Easy to switch out the covers, so hard to determine when the switch was made. However, I submit the following pictures from a current Ebay sale (which I am not affiliated with). It shows an NOS Bosch voltage retulator with a date code of 409. It's got a black cover.

Yes, I know about Mr. Mittlebach's car, but I'd love to see the date code on that VR. Watching VR's carefully, what I have not seen is a NOS silver VR with a date code that matches production of the 356 C's.

This one being September of 64 doesn't prove that the switch didn't happen right after that and if it did, well then a silver one could have been used during late C production, but certainly any car before then would have had a black VR, and certainly some right after this date would be black.
My 2 cents.
PS- I think the black VR on my previous car was something like 405, but that is no longer relevant. Certainly somebody could put a silver cover on a VR that was originally black, so NOS parts are the best determination at this point- at least in my opinion.

Some 1964 356 C cars were built in 1963. Ruby - my car - left the factory in September of 1963. The two differences are:

1) Flat hub cap for the disk brakes - with no porsche emblem.

2) The front hood latch panel is flat - no indentations.
