thanks to all those that had a crack at it, but the solution may be solved, general consensus (after visiting my fav climbing store) is that they are MSR cams, apparently MSR made cams some time ago but after downsizing and reorganising and a modification to logo, they stopped the manufacturing of them, the other upside is that they appear to made of titanium, and as a consequence are worth a bomb, so it seems I may (and I mean may) have jagged it and gotten more than my monies worth. again, thanks appreciate it.
Rupert I will give that a go and I will try and check out the other suggestions also.
