330 x 50 x 150 mm, AN -10 fittings, so this one: R50193 http://radtec.co.uk/cat/Oil-Coolers/191

It's had about a years use before my engine spun a shell and filled the oil with bearing material. I don't want to risk reusing it, but I suspect if it was flushed out carefully it would be absolutely fine. From the outside it's in good condition, no leaks or anything.

Obviously buy it at your own risk.

£50 + postage (i.e. half the price of a new one).

Bump... still for sale.
