Vintage CCM Bicycles

Hi

I recently found these two bikes, I would guess they are 1960-1970 vintage but haven't been able to find a serial number on either one. If anyone knows when they might have been made or where the serial numbers might be located that information would be appreciated. I'm looking to give both away to anyone whose interested.

Thanks

(FYI, I also posted this on the Vintage CCM Facebook page.  Posting here as well since search engines are more likely to pick up non-FB information.)

Circa 1915 CCM Cleveland Model 436

Serial: 904435

Here is a picture of my partially restored 1928 CCM motorbike.

It was my grandfather's bike.

I am presently trying to locate rubber blocks for the Gibson pedals.

Also, any suggestions on how to increase the tension on the seat springs? Has anyone tried to change them?

The seat is a Person's company seat. Probably the original seat.

Hi everyone. I happened to find an old bike that I thought looked interesting. It has a 3 piece crank, and a CYCO label on the down tube. I don't have much experience with these older bikes but I haven't found another adult CCM with the 3 piece crank. I've read that the cyco line was bargain line. The frame seems much better than a mid 60 rambler, so I guess they can't be all that bargain.
Anyway, I figured it is something to check out. Thanks.

Does anyone have a wartime bike with a decal other than the CCM decal? Looking for a reference to learn where this bike may have been sold
