Thank you. That is the one that says it is for a 206 on that Ebay site.
Yes!
I just received that exact key you cited in the link and it is to fat thickness wise to fit the ignition. There went a few buck down the Morgan Loo.
In the meantime I found one that works but have no idea on what it was primarily designed for. It came out of a computer read/scan of my Morgan key and a subsequent cutting. $1.50 :-)
