That's a big boy bike. Looks like it's greater than a 60cm frame. Maybe a 62. If it was mine, I'd ditch the drop bars & safety levers & install some nice upright bars on it. New brake levers & grips. Leave the stem shifters alone. Clean, polish, install new bearings & re-lube. Replace the chain & cables. Put a rack on the back. And, sell it for around $225. "As - is" after cleaning & tune up maybe $50. Be good. Have fun.
