Stamped drop outs, claw derailleur hanger, Shimano Tourney derailleur, steel crankset, steel rigida rims = entry level bike. Downtube shifters and quick release hubs front and rear are a plus.
For dating the bike, just look up the component codes on either of the derailleurs or the crank arms at the vintage trek site.
