Bernina old-style piping foot

[starry-diadem.livejournal.com]

I've got a Bernina 1001 machine (elderly these days, I suppose, but still a great machine) and I'm trying to find a piping foot for it - a number 38 foot.   I'm watching Ebay, but no luck so far.  If any of you have ideas about where I might find one, or have a spare you're willing to sell, please let me know. 

Cheers!
