I once got one from a guy that sewed football field Astro turf together with industrial treadle
machine retrofited with a motor ,Wish I still had that one, it sewed thru saddle leather no prob.
This one appears to be made in the 60s , came with all the extra attachments ,
It looks hardly used, lady said it's been in storage 40 yrs I got it for $40.00
I'll need to clean and oil it
