If you look at the left rear of the receiver down just above the stock edge, you should see a set of numbers in 2 digit format. That will be the month and year built and go a ways in anything for your rifle parts wise should you need it. I have one dated 06 02, so June of 2002 but where the front of your stock is curved, mine is angled and not sure when they changed that.
Maintenance is as easy as wiping down the outside, stock included, after shooting with a bit of Ballistol. For the barrel, everyone has their preferences, mine is a Hoppes bore snake minus the bristles with Hoppes #9 on about 2 inches of the end. Couple pull-throughs and I have a clean barrel. You likely already know to check your stock screws, if not, you do now and springs have a habit of making them loosen over time so something to keep an eye on.
