Before the set I've just received arrived, I'd had two sets of the low-end wishbones through my hands. The first I bought in Germany in 1992 and had worn out by 1996. They looked like this:
No cable adjusters, and from above the lever looks like a straight thumbshifter with a second lever out of the side. The set which is now on my Inbred are the same, bought on eBay for £3.99 inc postage
The set I've just received are like the XCM / XCT / XCU wishbones pictured here, cable adjusters all present and correct and a lever which branches halfway like the XC Pro version:

As I say, I've never seen a set like this before, and I didn't know there were variations in the low-end wishbones before I started researching them today.
Though the three low-end groupsets above have the same wishbone shifter pictured
, the catalogue numbers are different. I would therefore appear to have two of the three low-end variants, but I have no idea how the third one differs as I've never seen photos.
Bear in mind, AFAIK, that wishbones were never specced OEM on any bike, which is a major contribution to their relative rarity.
