Thank you for the info, yes the lett is B but the last two numbers looks like it only was partly stamped this is what it looks like B852oo (and uneven jagared) right on the radius of the crank it could have been drowned in Panit ? I will sand it down and see what I find. Yes it looks repainted so I am going to get it Restored if it’s worth it please look at this photo and thank you for your information

Oh, then the last 2 are a 5 and a 0: B85250

{edit}
That serial number is repeated in 52 and 1957 but, by then it would be on the drop out so;

1952; 04/04 to 04/30 ------- B78698 ------------------ E99356

It might be a 1947
which, there's no day list just year. Yet I think that badge would be right for this time.

Incidentally, your other photo was so bright it looked white under the paint but, gray primer is possible in this period too. With all that grease and grim inside of the numbers it is possible it's not repainted. You should began you own thread in the post war or heavyweight Schwinn section for further answers.

Not sure what this frame is,

1589b16cdaef71b0ce6fab2727cf1d8c.jpg


I’m thinking multi speed Speedster, because the curved top tube and the cable guides, but....
For staters the serial # is: FJ565272
That makes it June of 73, right?
Can anyone decode the rest?

Thing is, the 73 catalog shows Speedsters as diamond frames.
Based on measurements, I’m pretty sure it’s a 26” bike, seat tube length from center of BB shell is 18”

Length of chainstays from center of BB to the center of the dropouts are ~18.5”

Original color appears to be Sky Blue

Any ideas?

Thanks in advance

It's for sure not a Speedster. My best guess with those cable guides is a 1973 small 17" frame Collegiate. Sky Blue was not offered so it may have been painted a few times.

SCHWINN WORLD CATALOG.png
Has anyone ever seen an original or copy of a Arnold Schwinn World catalog from 1900-1915? Have seen 1897-1898-1899 catalogs. Seem to be few and far between. Thanks Dave

I recently picked up a Chicago Schwinn 10 speed bike (says World on it), trying to identify the year of it. Found a serial number on the left rear, I have not located a matching serial number from the information out there. Anyone able to help? thank you.

That's not a Chicago Schwinn. Japan or other import maybe by Giant. If it is a Schwinn, the build date should be stamped on the head badge.
See if this site's info helps. http://re-cycle.com/History/Schwinn/SwnB_Serial.aspx

Thank you for the site reference. This helped - turns out to be a Taiwan made Schwinn - Circa 83. Serial number is on the right rear axle. The head badge does say Chicago Schwinn.

In the case of your bike that head badge reference to Chicago is where the company offices were not where the bike was built. Schwinn did that for years after they quit building bikes in the USA. Roger

Hello all... I am fairly new to the older Schwinn game and recently picked up a cantilever cruiser frame for a project. I couldn’t find any info on the serial#, which is Y6401229, on the left rear dropout. The head badge also has a 2436 stamping... any ideas on the year? It came with the more modern straight tube forks!

2436 means the 243 day of a year ending in 6. Maybe 1976 the first year this system was used at the earliest but could be 1986. 1996 or 2006. Pictures would solve this. The Yxxxxx means is is not US made. Roger

It could be a 1976 or 86 frame. Leaning towards 1986 because if the serial number you listed. The bottom bracket is not Schwinn but a 3 piece conversion kit. Hubs are off a different bike also a Cruisers didn't have quick releases. You have a Schwinn overseas framed frankenbike. Could be a nice rider but will never be very valuable. As it sits with the wheels and tires it might be worth $80 +. Roger

You built a modern "Klunker Mt Bike". A niche bike if its own and there are many people who like them including myself. That kind of makes the when the frame was bult not a real important question. Enjoy your ride. Roger

Thanks Roger... yep, the year really isn’t important to me, it was just curiosity!
