This is my most recent Featherweight purchase. Her serial number is AF941450. According to the ISMAC dating site http://www.ismacs.net/singer_sewing_...-database.html she should be a model 15. Not! The Featherweight 221 book authored by Nancy Johnson-Srebo gives the production dates of mid 1938 to mid 1941. I also know that it was not uncommon for Singer to allot a range of serial numbers for one model then run another model number. So I am going to go for an allotment date of 14 May 1941.
This Featherweight and her case are really, really clean for her age. The case handle is nigh on perfect. I did replace the drip pad which was smelly of course. All she needs is some surface cleaning.
I do have a question about the motor wiring which has some white stuff (efflouresence?sp) on it. It is the first time I have seen it. Is it a problem? Otherwise the wiring is what I would term excellent.
There was quite a little collection of parts in the case top including a "what is it" in the last picture. The red seam ripper has the name Necchi on it. Is the silver bar thing also a Necchi part of some sort?
