I am all sorts of confused now. This thread has been inactive since before I joined QB. I'm surprised I did not find it when I was researching for my 15K. I know the opening poster's machine is not a 15K-30 (improper) or 15K30 (proper), because according to
https://www.sil.si.edu/DigitalCollec...es/image30.htm the 15K30 is for light manufacturing and has wheel feed and roller presser foot.
I thought that the machine that I have was probably a 15k26 or similar. I was basing that pretty much on the parts list that can be found in several places on the web such as
https://web.archive.org/web/20190727.../IPpartCharts/ and title includes 15K3_4_24_to_27_70_to_73_80_to_85 according to that parts list, which is undated, all the bobbin winders are attached to the belt guard. So back to the 1907 Kilbowie catalog at the Smithsonian website the domestic machines start on
https://www.sil.si.edu/DigitalCollec...es/image27.htm and have the bobbin winder on the pillar.
The only thing I know for sure is that my machine is a 15K (by the serial number) and the bobbin winder is on the belt guard cover. I have also determined that it is a K designation because stitch length is down to increase the stitch length, whereas the US 15s of that era the stitch length is the opposite direction to increase the stitch length.
I have seen a couple of advertisements that are for the 15K26 and since they are just drawings, neither has a bobbin winder shown at all. One such advertisement is
