This morning I found some answers.
My S66 C2283439 is a model D66 made in 1922 at the Wittenberge factory in Prussia. That’s nice!
But what does it mean that C and the rest of numbers? Maybe the 22 indicate the year of Its creation, but the others?
but the answers always arrives on time, right?…
Yesterday evening I got a great advice from an other Singer-lover (grubbe77 at Instagram. She also has a beautiful lotus-painted Singer machine. An adorabile one! She write me that I have to get a metal polish steel wool for cleaning the rusty parts of my S66. Deep in my heart I would let on It all the dust of history, but I think that Its earlier owner would be happy to known It clean.
I wish to find out who used the machine before of me.
