I know this is an old post but I stumbled across it and thought it all looked pretty similar to a 205-64 Adler I had as it seems to be a needle feed machine rather than the a 441 style with walking foot. Coincidentally I wanted to fiddle with the foot a little to get it to be able to sew closer to edges. As you can see the Adler foot was not chicken feed. You'll laugh but I found one of my 133K13 darning feet fitted the bar perfectly and I was able to grind and polish it to make a nice foot with one toe very short and almost missing..
I am in Australia but in desperation prior to my 133k13 foot find I ended up conversing with a Barb Hershberger at Weaver who sent me the following:
