Here are some up-close photos of the mid-30s chainstitcher that I'm tuning up. One interesting thing (especially compared to my Consew 104) is that the Singer Simanco mark & part number is stamped on most every piece of this machine. Dunno if this is true for the entire US run ... but you do see a lot of "Singers" coming from overseas w/o this stamp. Even the casting here has a Simanco mark.
Cool slotted nipple to better eject fuzz.
Wonder if this isn't stock or if all the needle plates were coming from GB at this time.
Whoops. Turns out the Singer's base is a little bigger than the Consew's. :)
