Classic and Vintage Bicycles: What's it Worth? Appraisals and Inquiries - 1980s Schwinn?? (I would like to ID the maker as well)

Does anyone have any information on this bicycle? The serial number is S91060074 (engraved in the bottom of the bottom bracket)

There are also stickers on the frame that say Cromalite 503, Built in USA, and Identification # A2184936

Not a Schwinn. Maybe a USA built Raleigh? Doesn't appear to be original, so hard to tell. Take close up pictures of all of the decals and stickers.

Seat post size?

While we're on the subject, how about this one? I've seen two other photos of this decal set in two months of searching.

The frame was built by Giant Taiwan in April of '78
Shimano and Suntour components.
I know it's a cheap bike; I'd just like to know what it is.
The suicide lever releases have Schwinn stamped on them, but that's the only place that name is mentioned.
The serial number, on the bottom of the BB is 80 21126

Your second bike is a Schwinn, imported model. I have a 1973 World Voyageur. The second bike is not a World Voyageur, but mine has the same headbadge. Let the Schwinn experts weigh in on it, its a pretty decent bike. The first bike was pretty much entry level, without a lot of original features, making it less desirable.

Especially the top tube/seat tube joint. The tips of the seat stays were done in a particular way. This does NOT look like a LeTour or World Sport, also the rear dropouts have a different, elongated shape from Schwinns. Must have built a couple hundred of them back in the early '80's.

Dia-Compe brakes
Sakae chainrings

The back wheel is Weinmann, and the front is a Méxican replacement.
Schwinn approved brake levers
The stem is stamped SR
The seatpost measures 7/8" with my micrometer.
Suntour shifters
Suntour Spirt front der.
Shimano SIS rear der.

Anything else?

A photographer I am not.

Thanks for the extra photo's. The seatstay pic shows it to NOT be a US made Schwinn, the tips of the seatstays were pinched/crimped from the underside into a more triangular shape and there was a vent hole punched or stamped on the inside of the stays that you could see under the seatpost clamp. The dropouts don't look familiar either, I think (?) most of the stamped Schwinn dropouts had two eyelets. The full bike picture doesn't have the familiar shape that I would instantly (subconciously) recognize either.
One other distinguishing feature of '80's Schwinn lugged frames was a 1 piece head tube with the lugs cast into them. The simulated lugs were "thinner" on the head tube but thicker/normal on the TT and DT where they were actually brazed together.
Can't remember when they started ('83 or '84?) putting "lawyer tabs" on the inside of the fork blades. A tab was mounted inboard of the locknuts on each side of the hub that would pivot around and snap over a phillips head screw that was threaded into the blade. Schwinn forks of the era would either still have the screws (I left mine in) or would have threaded holes (4mm?) about 2 inches above the dropouts. A matching hub would either have the tabs still or would show a distinctive locknut with a round "step" cut on
the inside around which the tabs would pivot. Hopes this helps!

Well, it helps, I guess, to know it's not a Schwinn, but what I really want to know is what it IS.
The frame was built by Giant, in Taiwan, in '78(G0478) on the rear dropout). Did Giant direct market any of their bikes in those days? I guess I could be happy just knowing it is a '78 Giant, but I know full well I won't be able to rest with that. Somebody out there must know what it is. It has a barely legible sticker from Helen's cycles in Santa Monica. PS It has square holes that the tabs fit into.
