Weber finishes and fuel line details for 1967 911S

[1QuickS]

I've just completed a project for a 67S Targa that has 40k miles and one owner. Car was parked inside in 1988 and has just begun a new life. I found several interesting finish variations that I thought would be of interest as well as an original fuel line so the ferrules (crimped and slip-on) could be observed. The fuel line even has remnants of the paper sticker used for parts identification. The manufacture date was the first week in June and the carbs show evolutionary changes as the 1968 model year approached.

In no particular order:

• throttle bodies are as-cast aluminum and not treated with the yellow/gold finish
• air horns are nickel plated
• long throttle shaft diameters are 0.0010" smaller than the short shafts (shaft bushings were sized accordingly)
• short throttle shaft end plates are finished in silver zinc plating
• SEMS screws for high speed enrichment tube installation are silver zinc plated
• accelerator pump cam lever, top cover pin and the roller lever arms are silver zinc plated
• all spring steel pieces are black oxide finished (typical)
• remainder of steel components including throttle body studs are yellow finished zinc plated (main venturi grub screws were usually black oxide for earlier carbs)
• accelerator pump cover is early style without the reinforced edge
• the "folded-spring" shaft coupling is the updated version before the cylindrical coupling was adopted
• the accelerator pump cam-lever arm is the later style, IDA type with the longer lever arm
• the idle jet holders are the early style, non-o-ring type
• the mixture screws included the cup washers with o-rings (used on later carbs)
• included are the rare to find, brass washers used between the air horns and the nylock hex nuts
• the accelerator pump rod is the adjustable version unlike the earlier carbs used
• the fuel line ferrules used at the nipples on the banjo fittings are Cohline and are slip-on and not crimped
• the fuel rail installed across the rear cross member uses crimped ferrules for securing the fuel lines to it

Look gorgeous... Weber porn in fact. Not exactly stock, but even a concourse judge would have to give points for the sheer beauty.

How are they not stock beyond the safety wire installation? I started to install OEM style safety wire but couldn't come to do it so I reverted to aircraft style; otherwise carbs are exactly as removed from the car. Educate me, please.

Oh, lead plugs are a little different than OEM, mine don't have the nipple in the middle.

Just never seen them with the nickel plating and looking so nice. Did not think the plating was stock.

Earliest Webers had nickle plated horns, later ones were zinc with yellow chromate finish, these would be for 69 and newer yer models. Zeniths also used the zinc plated horns as well as black and grey plastic ones. Also, the earliest steel horns (including the zinc plated ones) were spun from one piece; flanges and horn are all one part. Later horns were furnace brazed from two pieces.
