Gomog, you seem to have missed the point..
That happens often.

I was thinking it was a device to protect the very low, fragile sump from any impact.
The clue is in the word plough. The idea is that it might sweep away a small obstacle,
And how does it do that and why would that help with the dangerous issue of a low slung fragile sump?
there's no claim that it will absorb head on impacts.
Actually, there have been many claims here that it will do just that, but I won't argue with you.
BTW, if you are right, why bother with it at all?. It will merely lower and spread the low clearance by many, many multiples..meaning users will impact more often. And any impact over that much larger low area will be transferred to the sump. Kapow!
Anything that reduces the anxiety of minute road clearance on the early roadster is definitely a good idea.
AGREED! But this plough has a negative effect. But I admit to having advised some owners to paint over or disconnect the Morgan gauges that agitate them the most. For example, by the time you notice you have no oil pressure on your gauge, your engine is seized. Why worry except when changing your oil?
In my opinion the sump being so low on modern Mogs is driven by the legal requirements to increase the distance between the bonnet and the top of the engine...to protect any pedestrian who finds themselves resting on it suddenly at speed. Nick
Interesting. But I have become completely prepared to believe any reg governments pass these days.

You mean the distance between the top of the engine and the bonnet is government presumed to create a safety zone to protect pedestrians hit at the front?...
or front and back? The group can decide the logic in this.
As a historical note, Maurice Owen, the MMC designer from 1967 to 1991ish) EFI Morgans Plus 8s couldn't figure out to easily get the plenum under the bonnet hinge, or the air filter holders under the bonnet with SU carb Plus 8s. IN the first case, he cut the bonnet hinge. In the earlier case, he had them hammer the SU air filter holder flatter with a hammer.
Bill Beck sorted this stuff when HE took over from Maurice. But we are giving grounds that Beck's lowering of the engine, was no favour for Roadsters. Even the modern day MMC is hobbled by not knowing what came before.
.in fact, even denigrating it .
When I received my re-created Plus 8 from Malvern, I noticed that the Beck setup did not require me to cut the bonnet hinge! I was working with Bill then, he had been sent over to help me assemble my last remaining Morgan and was living with us at the time. We talked at length about his changes and ideas.
Great fun over a nightly bottle (or 2) of wine. Here are images for you.
