Hi there,
I've just picked up a completely unused, never assembled 12G940 Cooper S head for 701 New Zealand dollars, which is roughly 380GBP. I'm feeling quite happy with the purchase but thought I might as check to see what they're actually worth. I'm pretty sure it really is a Cooper S head since it has 11 studs and bigger valves than the standard 12G940 I have lying around. Here's the link to where I bought it: https://www.trademe....x?id=1411005469 So tell me, how did I do?
Cheers,
James
