I'm asking £40 plus £12 postage, so call it £52, no offers, I'll keep them if no interest. PayPal payment please. UK only thanks.

They are tested and work fine, but due to their age are sold 'as seen' with no kind of assurances.

Thanks Barry :).

The 'gunk' on the back lip of the driver rim is only BluTak and just peels off. I had left the drivers as they came to me.

Bump for these interesting drivers.
