Thank you all for your advice and comments.to answer Bob Culver's comment, the outer race is a reasonably good fit in the housing, but the inner race is only a little tighter than a good push fit on the crank. I can't turn it on the crank though, and neither the old bearing nor the crank shows any sign of rubbing. Both the old bearing and the new bearing are about the same fit.
I shall speak to Jamie this morning and possibly ring Hoffmann Precision Bearings at Huddersfield to seek advice. The extra rollers may extend the bearing's life. The old one is probably about 50 to 60 years old, but the car did very little mileage during that time and was laid up in a warm garage for 25 years prior to me buying it.I have some Loctite 641 bearing fit, so I may coat the crank with this prior to fitting the bearing if that is what I decide to do.
I think I have worked out how to fit it. Put a cable tie round the rollers whilst I tap it into position making sure that it all goes into the outer race without jamming.
I will post again when I have decided what I am going to do.
