"Is that from a '37 Zephyr or a '46 Continental?"

The Lincoln-Zephyr V-12 evolved over its thirteen year production run. Many
of the components -- air cleaners, carbs, intakes, oil pans, waterpumps, fans, generators, etc. -- changed from one year to
the next.
On this page, I will post pictures of *'37-correct* components to help
other restorers ID what they have or what they need. Like always, if I make an error, please let me know!
To the dismay of restorers everywhere, the 1937 L-Z had a unique
air cleaner that was often discarded and replaced with units from later years. The following pictures show an original
standard air cleaner. (When I get a chance, I'll post pictures of an optional, ultra-rare oil bath cleaner!).
The below pictures show two 1936-7 intake manifolds. The one with
the rougher looking exterior is actually NOS, as you can see from the perfect-looking underside. The other is off of
a low-mileage car and is in excellent condition.
Both intakes have the "H6520" part number. Also notice the smooth
carb "stump" with the two barrels and holes for a three-bolt carburetor -- later replacements look *much* different. However, even
these two differ slightly in their casting details.
The next two pictures show a 1937-style oil pan. As the pictures show,
it differs from later years in that the oil plug is on the *driver's* side (I don't know if it differs from a '36 pan -- anyone?).
You can also see a screw plug, likely for the external oil filter, which was optional in 1936 and *maybe* the first part of
1937.
Below are two pictures of the '36-'37 style waterpump versus the later
style pumps. As you can see the "shoulder" is rounded on the earlier version, resulting in a smaller oil reservoir.
In addition, the earlier driver's-side version doesn't has an opening in it. I was told by someone that this was for
the later optional hot water heater system. Of course, since the earliest Zephyrs had hot *air* heaters, this setup
wasn't needed.
