More Downright Blows

After a bit more research, I've found some easily referenced text for Silver's works, and I've done a search for "down right" and "downright". Here they are:

Paradoxes of Defence:
"Surely, I think a down right fellow, that never came in school, using such skill as nature yielded out of his courage, strength, and agility, with good downright blows and thrust among, as shall best frame in his hands, should put one of these imperfect scholars greatly to his shifts."

"Whereby it grew to a common speech among the countrymen "Bring me to a fencer, I will bring him out of his fence tricks with down right blows. I will make him forget his fence tricks, I will warrant him."

Brief Instructions:
"In this forehand ward keep your distance, & take heed that he deceives you not with the downright blow at your head out of his open fight, for being within distance the swift motion of the hand may deceive your eye, because you know not by which side of your sword his blow will come."

Now, obviously that stuffs my theory of the editor changing the text as there is only one mention of a "downright" blow in Brief Instructions, and no mention of a "down right blow", whilst Paradoxes has both and in rather strange places.

I think the best evidence for the two versions of downright being the same though is the one my instructor gave to me: the first mention of "down right" that Silver makes.

"a down right fellow"

Now presumably Silver wasn't talking about a man that is down and from the right.....unless he meant someone who is depressed and right-wing?

Thank you, and goodnight.
