Hi it’s a Toyota sewing rs2000 sewing machine that’s all I know . I had it given me as a the person wasn’t using it any more .. yes sorry I didn’t explain that too well..I was wondering if I could sew 2 layers of 15 oz canvas so I could makes bags jackets ect ect .. and yes the veg tan is 4 mm thick (10z leather ) I sewed on piece of denim to. The leathe4 and it didn’t skip a beat ..I then sewed 5 layers of denim and it too was flawless
Cheers
