Eureka, thanks Ruairidh, the leaking seal is a Grufero TC 48 x 72 x 10 it was one of five supplied 7 years ago 4 loose and one in a replacement seal plate which was a NAK 1.875 x 2.875 x 0.375. It was the NAK seal I referred to when repairing the flywheel boss 0.020” undersize and eccentric which a Speedi sleeve couldn't do. So the NAK seal should do the job. The Grufero 48 mm seal seal is 1.889” and to fit that I'll need a Speedi sleeve. The moral is to check everything. Which confirms Leaf200's point.
