Singer model 15-30 parts identification
 

I was hoping I might get some help to identify some parts/accessories for my "new" Singer model 15-30? Serial number S1363154 dates it as 1907.

I can take more picture if needed.

Any help is much appreciated.

Pics upside down.
 

I don't know why my pictures are upside down, but if you click them they are right side up. So confusing.

Thank again for any assistance in my parts identification.

I believe the foot on the left and the plate looking piece on the right are parts of an under braider. There is a video on you tube showing you how to use it. I have no idea what the other pieces are.

Ok, just to update everyone I have figured out what all the accessories are except for the two metal pieces with cork around an opening. When looking at the picture full-sized and in the correct orientation they are:
1.The foot on the bottom is an attachment foot, all the assorted binders and hemmers hook onto it in order to be uses
2.The top right item is a quilters guide, the U shaped bit on the right side hook to the back of the attachment foot.
3.The top left and bottom right pieces go together and make a tucker attachment, I have found only 1 picture of it assembled thus far and that person had it dated as a 1901.

Thanks for stopping and looking.
