Needing Marbles Knife Info

[Arcticmanak]

I found a Marbles Knife for sale, very similar to this one pictured. I think the model may be Woods & Water. If anyone is familiar with this model I'd sure appreciate some info. I like the design, and seems very close to a Randall Alaskan skinner in some respects.
Are the Marbles knives known for good steel, worth buying, reasonable price....?
Thanks!

Antique Marbles were excellent knives in their time, iconic and collectible now. Not really worth carrying unless it simply has sentimental value to you. Much better options nowadays.

Contemporary "Marbles" knives are just junk.

I'm not interested in the modern made in China lineup. I am trying to verify where this one was made and from which era of Marbles production.
Are all of the models made in USA stamped to indicate that?
