Classic and Vintage Bicycles: What's it Worth? Appraisals and Inquiries - Unknown Schwinn Road Bike and Giant Kronos Road Bike

I would appreciate a little help on these two bikes; I will try to get some photos up soon. Thank you.

Schwinn
Chicago serial no. G83 8740. No model name. I don't know if it's been repainted. It's a deep rose pink that blends into white about halfway back the top tube. The crank and the brakes are white too.
Wheels- Weinmann 700c, Tires- Schwinn Prologues 110 psi, Crank- Sakae FX SLP, Derailleurs- Suntour Cyclone, Brakes- Diacompe UX, Hubs- Sachs Maillard.
Paint is very good with a few scuffs, overall bike is excellent.

Giant Kronos
Chromoly tubing, Shimano Exage derailleurs, Exage Action center pull brakes. Wite walls dirty, needs brake lever boots and a good seat, seat is a funky Schwinn wide one. Frame paint is dark blue blending to gray and excellent condition.

Thank you very much.

Photos would be a big help.

On the Schwinn, look closely at the head badge for four small, lightly stamped digits. They represent the assembly date. The first three digits are the day of the year (001-366), and the last digit is the last digit of the year (8 could be 1978 or 1988 for example - the decals and components would tell the decade).

"Chicago" on the head badge doesn't mean the bike was built there as the Chicago factory closed in 1983. Schwinn's headquarters remained in Chicago until the late 1992 bankruptcy, so the "Chicago" on the head badge represents the HQ location of the company, not where the bike was made.

+1, lots of Schwinns not made in Chicago have a "Schwinn Chicago" badge. I wish they didn't do that. It causes endless amounts of people to think and advertise their bike as being made in Chicago when it really wasn't.

Condition is everything for the value of a used bike. Without pictures I will not even take a guess.

Actualy the color starts out white at the head tube and blends into the deep rose as it goes back and the seat tube Says "Wild Child" (painted). It seems unusual that the brakes etc are painted too. Does this indicate a later custom paint job? It seems to. The serial no. came from the bottom bracket.

White brakes and cranks could mean they are Shimano Sante components or the Suntour equivalent. Suntour offered Cyclone groups in white also.

The serial number on the Schwinn doesn't seem to be a regular Schwinn serial number. This means the frame was likely built by another company for Schwinn a lot of the road bikes sold by Schwinn where made by other companies. My best quess is it was built by Giant for Schwinn in 1983 based on the serial number.
