Long shot - Class 11 up-the-arm parts

[rlevine]

This is a _very_ long shot, but I'm always optimistic. 

Can anyone suggest leads on a set of up-the-arm needle plate, feed dog and presser foot for a Singer 11-16 or 11-26? 

I have an 11-26 that I'd like to run as an up-the-arm zigzag.

(Yes, I do have some queries out to parts jobbers, but you folks often come up with great ideas I didn't think of!)

Part numbers are:

• 12081 feed dog
• 12082 half-coverage presser foot
• 12083 full-coverage presser foot
• 12084 - needle plate

Parts-list picture attached.

Thanks!
