Wanted: Remote Cords (Trigger Cord M)

I don't suppose anybody has a Trigger Cord M (or more than one) by any chance? I think that was the correct name for them, they allowed for the connection of multiple cameras with winders (MEII with remote cord M) to be operated simultaneously. Or does anybody know where I could find some, have tried ebay but perhaps I am using an incorrect name when searching or are they just really rare?

Any help much appreciated, Thanks

Bojidar's website gives:

* Trigger Cord M - Attaches to the release socket of Ni-Cd Battery Pack LX or M on one end and to a remote-control accessory on the other. As a special application, two such cords can be used for simultaneous operation of two cameras.
* Winder Remote Cord - connects to the release socket of Winder LX and Winder ME II. Can be used to release the camera's shutter.

I have seen the latter on ebay but never the former, so I guess they are quite rare.

Best wishes, Kris.
