These shuttle controls came off a Matbro TS280 (R reg), but I am sure would fit matbro's of a similar age. THEY DO NOT WORK but can be easily repaired.

The story is that they are for sale as I do not have the Matbro any more and I found these in my workshop and thought they may be of use to someone. I kept one of them as a spare that I was going to repair and keep as a replacement. You know how it goes.........I never got round to it and the second one went and I had to buy a replacement in a hurry. Not long after that the Matbro went up in smoke. Hence I had these two kicking around.

All that needs doing is a new micro switch soldered on the end of the wires in the lever housing. My local dealership used to mend many like that. There is a new microswitch included with the two units. A 1/2 hour fiddling with a screwdriver and soldering iron (cost £10) and you have a replacement unit. A spare microswitch is available off ebay or local domestic elecrical supplier for a few quid to repair the other one. 

Sold as seen.
