A windage tray and a scraper are not exactly the same thing. The scraper is a
piece of metal shaped to fit close to the crank so it can scrape off the oil
that gets wound onto the crank. The windage tray may incorporate a scraper,
but it's a cover that fits between the crank and the oil pan intended to keep
the oil in the sump from being blown around by the wind generated by the
crankshaft. The motor I built for Peyote has a windage tray, a scraper, and a
baffled sump, all aimed at getting oil off the crankshaft and down into the
sump.
And it's pronounced windage as in blowing in the wind.

Is that where the term "windage tray" comes from? Is it pronounced windage
like Kentucky windage or like what it takes to wind up a toy?
