This is my 'new' machine - I only got it last week at auction. It is also the third of my vintage Singers.
It is near perfect condition - practically no dust or oil build up. It has a serial number of JC186606 and appears to be a 128 - the 3/4 sized version of the 127 (my treadle!)
What is a little strange, and needs more research, is that the serial number appears to relate to 1948 machine. However, it has a badge on it celebrating 100 years of Singer Machines - 1851 - 1951.
The decals on this machine are called 'Celtic Swirl' - rather fitting as this machine was manufactured in Clydebank, Scotland.
It appears that a previous owner has scratched their telephone number into the body of the machine. There is the faintest indication of rust here, so I will need to look into that. Hmm, I've just looked up '612' and that is the dialling code for Minneapolis, Minnesota, or Sydney Australia. The plot thickens!!
There is a handsome silvered badge on the back, and a bolted on light and motor.
The side plate is quite stunning - a grapes and vines engraved pattern.
This is another reciprocating shuttle, and as can be seen, it is spotless!
Finally - here is the cover, complete with a key and a sticker on with the auction number and my winning bid number. My 99k also has a similar carrying box - and I have learned (not through experience, thank goodness) that the handle should NOT be used as a carrying handle as it cannot hold the weight if the machine - the handle is purely to lift off the cover!
I used Singer and ISMACS to help date the machine and this site to determine the model.
