Pedal powered 6 class Singer?

[DonInReno]

This isn’t a great picture, but what appears to be a gear-reduction, two foot, pedal powered treadle is directly connected to what I’m guessing is a 6-class Singer of some kind.   Has anyone seen this setup before?   ISMACS didn’t seem to mention any geared treadle in the 6 class info.  It’s relatively compact and might make a fun curio for someone’s sewing room.

That looks like a 7 class to me,that has missing parts that make the foot lift when it walks.Poor thing has had a rough life,looks like some treadle parts are missing or broken too,which will be real hard to find unless you are able to make themHere's a pic of a 6 class we have,you can see how much beefier it looks.

Interesting - thanks for that picture - six class is much beefier in a photo than the few drawings I came across!

This machine is listed on eBay and is in Salt Lake.
