My buddy has a Florence sewing machine, not entirely sure the mode because information is a bit limited. Something in the crown line. I did a bit of research and it seems to be newer than 1880's when the company came back. So onto the wild questions, think it can sew 2 layers of 3 oz leather with a leather point needle? (And what kind of needles am I looking at) Maybe too much to ask, and maybe a bit dirty if the machine is rare. Here is a picture from my buddy.
