:D ive seen these on E bay but the ones for the Triathlon are like male and female allen bolts that fit in to a recess on the frame.the adjusters are like a flat head screw but they are sprung and have a brass knob on the outside of the drop out,Thanks for your input.
Allen key seat bolt? Here you go....

....or a decent LBS should be able to supply for a similar price. The dropout adjusters sell for about 6 quid a pair upwards from (as a "for instance") SJS Cycles in Somerset. Not as easy to come by these days though with vertical dropouts dominating the new-frame market.
