It's one of the 4 early 150 series electrics (earliest O-Gauge engines made by Lionel?). They all look almost identical, strap headlight, Bell, body shape. The lack of journals (or slots to attach them) implies yours is a 150.
In that condition, it's not worth a lot. If the wheels are crumbling from zinc rot, not much at all (4 wheels cost ~$40). Good wheels, a good repaint, and good running condition may fetch anywhere from $50 to $100 on eBay. A top notch restoration may double that.
TTender.com has many replacement parts (e.g., wheels) for this loco.
