Nice collection!
Several of your reels look similar to this, which was my very first fly reel that I bought sometime in the mid-1950’s. It is not labeled except for a stamp on the reel foot that says (proudly) ”Made in U.S.A.”
I don’t recall ever catching a trout with it, but maybe I should get it out and fish with it - like your’s, it is fully functional.

It's bit difficult to tell from one picture,
Possibilities would be Hendryx, or one of its successors ie Winchester of Horrocks Ibbotson- though the knob handle is a bit different. What does the back look like? Is it possible some other identifying marks are worn away. I have a similar model that again except for the lack of manufacturing ID it would lead me to believe they are of Winchester or HI origin.
