Vintage Pen Mail - A Hi-Writer and an unbranded lever filler

In pen mail today, I got two vintage additions to my collection. One is a circa 1920's or 30's third tier manufactured Hi-Writer. I have not been able to find any information on that brand in all of my searches. The other is an unbranded lever filler with a hooded nib, probably from the 1950's. It reminds me a lot of a Universal brand pen I have in its construction.
