Crankshaft pulley for a BMC 1.5 diesel

That's because it was *replaced* by the larger variants. It was overbored to 1588 then a major redesign to 1622 with a larger crank. The 1798 a development of that - before getting 5 main bearings. Although two sizes may have been available at the same time, the 1500 was dead and buried long before the 5 bearing came out.

Basically a B Series.

Both 3 bearing. There were three different 1600s fitted to the MGA if you include the twin cam. IIRC, the 5 bearing was developed mainly for the 'Land Crab' 1800 saloons.

I recall that Car magazine tested a Morris Oxford (Farina) diesel. The picture was of a Farina, covered in cobwebs and apparently in a scrapyard. Part of the text was "I started it up, and omigawd the bigends have gone". The good days when the irreverent Aussie Doug Blaine was editor.
