I don't want it thanks, but I may be able to help identify it - is there a number on the back of the arms in a square or circle or similar?

Xenon.

you've got the outer ring in the wrong place,that pin should be behind the crank arm.

Hi, Thanks for responses. The number on one of the cranks is 24.
Realise outer ring is in the wrong place.

Might be Xenon, might be something more 'exotic' - how much detective work do you want to do? I posted this on another forum recently, might help here. It's a bit of hard work but try to identify them through these:

It will help in the cross reference if you can date them: on the back of the arms, there may be a number in a box, or circle or diamond (or something similar). Starting in 1973 the crank arms have a code consisting of a diamond (1970's) or circle (1980's) with a number in the center denoting the last digit of the year of manufacture, and then in 1985-9 with square and number in the center: 11 = 1985, 21 = 1986, 31 = 1987, 41 = 1988, 51 = 1989 plus some other examples.

Wow thanks for this.
It has a circle and 2 raised dotes that obviously indicate something.

Looks like 1980 - but I'm not 100% confident!

eta - I'm talking out of my backside, it can't be 1980....
