A strange crankcase can you help

[Tony Press]

There was one like this on eBay not long ago i.e. 2 bearing but in a 3 brg casting. Not sure about driveline height though.

Tony B - I don't usually come up with wild guesses, but I do know that un-numbered crankcases were available form Longbridge as replacement for damaged ones (and maybe also for OEMs, for eg the early G.E. Brooklands had their own numbers, not the M - type).  The numbers stamped into the case 21532 denote the date 21.5.32, so maybe this was one updated elsewhere for a later car?  Sounds ridiculous, but perhaps I'm entitled to some insanity occasionally?  Cheers,  Bill

Bill,

Interesting bit of lateral thinking on the number !
