I found this bike on CL today and bought it on the spot. No pictures yet, too late at night. I'll load some this weekend, but here is a description:

22.5" c-t, medium blue metallic paint, TREK letters on both sides of the seat post without any background color around them, no model number anywhere on the frame
Reynolds Tubing decal on seatpost is worn, I think it says 531 but can't be sure
Reynolds tubing decal on both sides of the forks is clear - 531
Serial number on the BB is H3F921
derailleur cable routings brazed on above BB
Campagnolo rear dropouts
Campagnolo headset
Campagnolo crankset, chain rings, and BB, arms are marked Strada
SR pedals
Campagnolo hubs, skewers
The rims are unmarked except for a rectangular decal, black lettering w/gold background "GENTLEMAN"
Suntour Superbe (early version) FD and RD
Suntour Pro-compe freewheel
SR seatpost
SR Royal stem
Sakae Custom bars
Dia Compe Gran Compe centerpull brakes and drilled non aero levers
Ideale 90 seat
new Continental Sport 1000 tires 700x23
weighs about 18 lbs.

The seller said is was an 1983 model, although he wasn't original owner, so who knows.

Any thoughts on what I have? I'm pretty sure it's a keeper as it is my size.

You will, after looking up the serial number here: https://www.vintage-trek.com/

Enjoy the bike!

(H3F921 = 22.5" model 710 from June 1979)

Thanks. With a little cleanup it should be ready to go. It's in great shape overall.

you got yourself a very nice bike! i forget who made those rims but Im sure someone will chime in

$95. Figured I couldn't go wrong. I'm looking forward to riding it and comparing to my Fuji Royale. It's about 7 lbs lighter.

$95?! I don't know whether to congratulate you, or call the police!

That was a fantastic deal. Congratulations (no cops)!

When I picked my a very good condition 1987 400T for $75, I thought that was the deal of the month. 710 for only $95, you are a very lucky guy.

Oh yeah, pictures or it doesn't exist.

A really nice deal, but, I think your weight is off 3-4 lbs. Ideal saddle and clinchers add weight, should be more like 22+ lbs. The rims should be Matrix.

You could be right on the weight - I did it quickly last night. The real test will be the ride. I'm a little concerned because I live in western NC and hills are normal. I have my current bike set up with a 39 tooth chain ring and a 14-30 cluster in the rear. Just about right for an old guy in the mountains. I didn't count the cogs on the Trek, but it can't be more than 24 - the Superbe RD won't handle any more than that I don't think. It might be more than I can pedal up the hill to my house. I also switched to Ultegra dual pivot brakes and like them a lot. I hope the Dia Compes are as good. We'll see.

Yeah, what he said.

H=710
2=22.5" frame size
F=June, month the frame was serialized
9=1979

A very nice bike at that price. Here's the brochure from 1979 which sorts out the 700-series a bit by component level; based on the Campy bits yours could be either a 737 or 738 or it could be a 710 frame sold to a lbs for build-up. It should be 531 tubing with Campagnolo dropouts, but they did kind of mix things up back then. My 79 510 is Ishiwata 022 with Campy dropouts and a 26.8 seatpost size which supposedly was used only in 1977. Congratulations you lucky dog. And will you please hurry up and get those pictures posted!!
