I went for it…. after experiencing the dreaminess of the little portable Adler, I was determined to find a 30-1, and through a generous reply from a nice chap who writes a really informative vintage & industrial sewing machine blog (http://ucansew2.blogspot.com/) I found a good source for used industrial machines in Florida, and guess what they had for sale…. aside from every sewing machine under the sun….
My Adler 30-1 showed up in Kalamazoo from Miami last week… I am now in pretty deep realizing what parts I am missing, learning what a bobbin tire is, thinking about not using the motor to operate the machine and other random this and that… first a call into the manufacturer with an antiquated parts request….
