The only odd thing about mine is the serial number indicates a 54cm, but it's a 56. Perhaps a cm tall, but it's worked for me since 2014 when I grabbed it off an eBay auction. My only grumble is it pulls right no-handed and has a tiny braze gap on the left rear DO. Doug Fattic offered to straighten it many moons ago for not very much money, but given that I don't drive these days, the bike just doesn't ever seem to have enough downtime to send it away.
You have the Trek lettering but it looks nowhere near as wide or deep. I wouldn't worry about. It's the bikes of my era that were known to crack. Then Trek went to the socketed seat lugs and dropouts, almost certainly due to the cracking issue.
