Singer 99K sewing machine attachments

I received a box of attachments for my Singer 99K sewing machine this morning. They are original parts that would have come in the box with the sewing machine when new, plus a Vanguard zigzagger.

I bought them from http://www.singersewinginfo.co.uk/, who I recommend if you're into vintage sewing machines.

I've been playing with a few of them today, but it'll be a long time before I'm even vaguely proficient with them: I can barely use the standard presser foot (shown on the far right) at the moment.  I shall persevere.

If you're really lucky, I'll do a series on the individual pieces.
