Hello all!
thanks so much all for your fast replies and interest, lets go get deep in the thing:
I went with the machine to a local shoemaker, he looked at the machine and doubt a few time and finally he affirmed that this is a perforating machine, not intended for sewing, but I disagree with him.
As you can see there is no shuttle or bobbin, so the big question is: can i sew with this machine?
About the model and serial number, i took a look at the 16 class machines, the one that Bob has posted is a 16 class for sure but if you look close to my machine, you can see that it has some differences like the big wheel and the central bar that i havent see in any other singer industrial model for now, im still looking for what class or model can be this machine, it would be great to find the manual or some more infos.
Here are some screens that show the entire machine and all its parts:
Thanks again all for your replies, i love this forum!
regards
