Might be some markings under the paint on the barrel near the chamber, the stampings tend to be shallow. But it's a Stevens/Savage/whatever 60/70 series (see
http://www.urban-armory.com/diagrams/savage67.htm for a partial list of makes/models). They haven't been made for a good while now, I'd say it's likely the example in the picture is older than you are.
They do tend to break parts, mostly the single action bar and the (cast aluminum) trigger plate extension that the buttstock screw goes into. They don't lend themselves to much disassembly type attention from owners- barrels are screwed into the receivers on many of these variations and are not easily detachable as is the case with later, more modular designs. They are a bear to work on, and the very first step in taking one apart if necessary after making sure it's unloaded (and it's not likely a DIY job) is to remove the buttstock. The buttstock screw puts tension on the screw and pin holding the trigger plate in place in the receiver, making them difficult to impossible to remove, and I've seen several examples all beaten up by owners who didn't know that. They should come with labels IMHO- NO USER SERVICEABLE PARTS INSIDE.
Worth about $100 or so on the used rack, and they do turn up fairly often- they were relatively inexpensive guns back when they were new, and sold in fair numbers. Some folks have had long life and good service out of them, others have had problems- it's kind of a crap shoot. I wouldn't count on one to deliver a lifetime of hard use myself, OPMMV.
As a possibly interesting footnote, the US military bought a bunch of them with short stocks (designated the Model 77E) during the late unpleasantness in Southeast Asia, with the intent to issue them to our South Vietnamese allies early in the US involvement in the region. A lot of those which actually did get issued broke as described above. Interestingly enough a good many of them seem to have been issued to US GIs (both Army and USMC) rather than Vietnamese village militia due to a shortage of available weapons in theater at the time. The 77E may be among the least known and most seldom seen of US military marked fighting shotguns. See
