Not an expert, and don't have time to get into it now, but will add later, KEEP IT, they continue to go up in value, and nothing is going to wear out, I spent 2 months giving mine a facelift. it was my first gun, but I made the mistake of leaving it with my Dad, he wasn't the problem, but he loaned it out to my nephew, I got it back, badly rusted (action cover was nearly rusted through, so I had to do something with it), some bad rust aroung the rear sight, and the stock scratched bad everywhere,
I was impressed with the simplicity of the internals, it has had 1000's of rounds put through it, the action design doesn't really leave anywhere for dirt, burned powder etc to build up, and it has never had any kind of failure, none, my first gun, got it for christmas when I was 9 or 10, killed many tree rats and cottontails with it, after taking it apart, seeing how simple everything is, them what impressed me was how accurate it always was, and still is, with the Zytel stock holding everything together, how could this possibly work?, don't know but it does, I'm sure it wouldn't work with a larger caliber,
I did some experimenting with textured paint and camo patterns, does not look like it did before, that's for sure,
Mine was the brown one, the chrome/black Apache is more rare, there is a green one, there is a bolt action one, and some of the semi-auto's are clip/magazine fed(detachable), instead of through the stock,
There are 5-6 variations at least, I think the green is the most rare, I was disappointed when later, after I had gotten mine, I saw the Apache, but only for a minute, I was just happy to have my first gun,
