Exercise bike ID?

[NLeming]

I dug up this old exercise bike conversion today. I looked at a ton of chain ring pics and couldn't find a match. Any ideas? Thanks in advance.

Looks like a balloon-era Westfield.
The 1/2" pitch chain, crank with a dive pin, and vertical badge holes suggests later; two supports between the main tubes suggests earlier.
The exerciser stand was likely an after market item; (e.g., Sears).

Thanks for the input. I believe you are correct. I uncovered layers of paint to see the serial #.
