This machine has the "Acanthus Leaves" decal set which was used by Singer on the 12K and 13K models.
An Ibanez serial number can tell you two things, year of manufacture and factory [or country] of manufacture.
The Singer 99k sewing machine is small in size measuring only 12-1/2" wide, this image shows an early version the 99K (99K21 - 26) made between 1924 to 1954. The stitch length was adjusted via a screw and the machine did not stitch backwards.
Later versions 99K31 had a stitch length up-down lever with reverse stitch and numbered tension dial - Year 1955 The Singer 15K is always recognised by its tension unit being on the left face of the machine.
It had smoothness that other sewing machine manufacturers could only dream about. The Singer 201K was cast iron in Black with a round neck body, also made with an Aluminium body which had a square neck.
The Aluminium body machines were made in Black/Gold, Beige or Beige/Brown.
The light aluminium frame was only 9-3/4" wide, even with the fabric rest down it still was only 14-1/2"....!
I'm sure its still the smallest adult sewing machine ever produced.
This one is a vintage Singer 12K sewing machine and was manufactured at the Singer plant in Glasgow, Scotland.the long bobbin/shuttle was inserted into its case which looked like a bullet, then the case was located into the machine and lay in a frame that looked like a boat hull.When the machine was running it most likely was quite noisy because the shuttle moved forward and backwards at great speed, at times it made the machine vibrate.The Singer 222K as shown has the sleeve arm or sometimes called tubular bed.The Singer 221K was the same machine without the tubular bed, it also had the lift up fabric table like the 222K Both the 222K and 221K were tiny machines known as the original Singer Featherweight machines.
