Wanted: Shimano Road Chainset

I'm looking for an older Shimano chainset for a tourer project.

Shimano 105/600 (others models considered)
170-175mm
Square Taper
I'm not too bothered about the condition of the cranks themselves.

Can anyone offer a chainset posted under £30?

Thanks

Not quite what you want but...Sora 50/34 compact inc external BB...hardly used.

Shimano 600 tricolour,170mm, square taper, £30

Thread Closed - Thanks Rik!
