Having a hard time figuring out the manufacturer/model of this old hand plane that I was given recently. No identifying marks aside from "Made in USA". Any ideas? Thanks for any help.

:eek: I am so Excited to buy a real handplane for the first time. I have a few really cheap ones from home depot that I have attempted to use in the past but after watching some videos on what a properly made and sharpened plane can do I am in love. However this is completely uncharted...
