Cheers Tim, a Type-20 Hawk. Very nice. Looks like the chap who owned it had a cleaning fetish

. The T25 was originally developed by Litchfield because the Spec C was supposed to be coming to an end and he wanted comparable performance so he went to the then new 2.5 bottom end from the States. He gradually improved the tuning of the 2.0 engine until they were returning very similar output to the original T25s.
Not many of either around in that sort of condition.
