No wonder I'm having so many problems. Thank you all for your responses and recommendations. I think I'll return the machine and look for something that actually works for me.

Are you referring to the attachments inside the red circle? If so, yes, it comes with them. The machine also has issues when sewing different thicknesses; for example, when transitioning from 2 layers of leather to 3, or from 2 layers to 1, the stitch length changes, and sometimes the presser foot doesn’t lift high enough to move from 1 to 2 or 2 to 3 layers. What kind of adjustments would be necessary for the machine to work correctly? Thank you in advance!

Hello, I do not live in the United States. I purchased this triple-feed sewing machine for $1,000 because the company told me it was capable of sewing three layers of chrome-tanned leather, each 4 ounces thick—approximately 0.5 centimeters in total thickness. They also mentioned that it could sew with size 138 thread on both sides. After using the machine for a few days, it started having many issues. My question is: do you think this machine is actually capable of sewing that thickness of leather with size 138 thread on both sides? It seems to me that the machine is at its limit, which is why it gets misaligned after about 30 minutes of use. The company did not provide me with any manual, only a small sheet with an unreadable list of parts. However, I found the exact model on a sales website in China. Any guidance would be very helpful.

Couldnt find any information online regarding this two machines, can they sew 4 - 5 oz chrome tanned, crazy horse? whats the maximum needle / thread size I can use with them? The owner wants $130 for the 12w10 and $220 for the 16-137 They are also ofering me this one for $220 they only know its a singer, but not the model, any help identifying it? Which one is the best option, or none, of the three? Any guidance and help will be greatly appreciated.

Came across this old sewing machine, the owner wants $150 but I have no idea what model it is or if its suitable for leather. Any ideas?
