I found a "G" part - full code "1 G 70" the other day.  I saw K and H discussed here, but no G so I figured I would add this to the equation.

John - Thanks  Don't recal every seeing a G. What we suspect was the suppliers code.

Thanks for posting a picture

I noticed the post and followed it though and see you have confirmed the D0AE-A PVS was used as early as Aug/Sept 69 on 1970 engines.
I would like to confirm that my 1970 428CJ R-code Mach1 Dearborn built on Sept 4, 1969, also has a D0AE-A with 7-H-69 PVS
I am curious what do the 1D2 markings on the opposite side define??
I bead blasted it and probably the wrong thing to do, is there any way to get the bronze shine back??

John,

In the picture you posted above with the G stamp does the switch on the bottom actually have holes drilled in it, or is that just a shadow?

Looks like it has dimples. Have those on many of the ones I've found over the years

The brass base with have to be polished and then appropriately dulled back down . The ported body is made of the same zinc based pot metal as a Holley Carburetor body. Without going into a lengthy tutorial you would refinish it the same way you would the carb body.

Thanks Bob, will need to figure out how to polish without damaging the finish on the non brass housing and polish wheel hooking on to the nozzles,
I asked the question about the 1 D 2 nozzle markings and assume those define the hose connections, but what are they?
1 = ??
D = Distributor
2 = ??

I've had some of those bowl type vibration cleaners/polishers. When things are set up I have one set up plastic, bake-lite and other parts in to clean and buff them. Just ground up corn hush (you can buy it bulk as bedding for small mammals) with some fine buffing compound added. Put caps over the ports in the part and leave them for a few hours and they turn out well (PVS) and are ready to be recoated for the upper section. The polished surfaces will dull with exposure over some time

Awesome great detail, thanks Jeff will give it a shot.
Any comments on the number/letter coding by the hose nozzles??

On pre 70 engine applications the routing of the ends is illustrated in the engine vacuum diagrams shown in the Library section of the site by year.
