Anyone recognise these?
Being the dge type internal fit, I imagine they must be around 1990. They look like a commercial product although the alloy parts have some evidence of turning, milling and cnc machining, so small scale.
Outside diameter of the wedge section is 19mm, which might offer a clue??
