Re: Intake Manifold without Pipe Threads for Vacuum port.

I bought it thinking it is an early one and since my '28 Roadster Pickup came with a mechanical wiper it might actually be correct for it.
It does seem odd though that they would have kept engines with and without tapped intakes organized just to match certain Models on the assembly lines when you consider the Volumes of Cars being built each day.

Is the manifold embossed in the location for the vacuum port but undrilled, or is it simply plain with no hole OR embossing?
FYI, 1927 and very early '28 (January?) did indeed have a 1/8" pipe fitting hole.
