Help identifying a PC cord

[xkaes]

I've run across a PC cord that is new to me -- on the right in the photo. I've tried to ID it, but there are so many styles, I figured it would be easier to ask the experts. My guess is that it is some sort of proprietary PC cord to go to a particular flash(es). Honeywell Stobonar, etc., perhaps? Here is a picture. It is short, has a male standard PC on one end and a two pronged contact on the other. I could just throw it out, but maybe someone through EBAY could use it. Looks like new. I've included a nickel and standard, household, electrical, two-pronged, A/C plug for comparison.

Thanks for any help, suggestions.
