70 coaster krate

Just bought this here on the cabe for a good price, The bars and the stem are stamped 70, springer is correct but the serial number is stamped on the rear drop out. Has anybody seen this before on a 1970 Bike.

Yep seen a lot of them. The serial numbers changed to the head tube in May 1970

 

[ADKBIKES]

they moved the serial number to the back part way into 1970

Yes, probably April or May 1970 went to the head tube.
Some on here claim to know what day it happened but suffice to say Feb 1970 is safe on the dropout still.

Up to mid 1970 was on the dropout.
Mid 1970 up was on the headtube.

I understand some '70s have both. Not sure if this is correct

Schwinn started stamping the serial numbers on the head tubes in May of 70. Here's a 1970 Twinn that had two stamped parts, a serial number stamped on the drop out and one on the head tube. I saw this Twinn many years ago and later my buddy Scott posted the Schwinn announcement that verified the May date.

That’s an awesome post….shows how (not) concerned Schwinn was with actual serial numbers during production.

With all the research I’ve done on the Schwinn serial numbers, they didn’t mean jack to Schwinn. They recorded the dates they were stamped and that was it.
