I'm not sure I understand what you mean by "quality".
From the pictures you posted it appears to be a hunting knife with a leather stacked handle, brass guard, stainless rear bolster. I cannot tell but it appears to be well used and the blade is probably some form of carbon steel. It appears to have some tarnish or rust on the blade, it is hard to tell. If the sheath fits that well it is probably made for the knife. All of those things are good.
Someone took some time and effort to make the knife. It appears to be of a nice quality.
Without a maker's mark - I would say it is a daily user and not a collector.
You just cannot definitely tell who made it. That is a big minus for its collectability.
