Recommendation? Most Desireable Models?

[TJDubya]

Howdy from Texas! I recently met a widow with a large collection of Schrade USA knives inherited from her late husband. After a discussion she offered me the awesone chance to see the knives and purchase my favorite. I know enough about Schrades to appreciate them, but not nearly enough to be confident in picking out the best knives possible in terms of value. Will those of you more experienced give me your opinions? What knives should I look for as a collector?

Thanks, y'all!
