I'm not an expert on the B33 but the 1955 B33 parts book I have lists the gear side engine shaft as 65-1129 rather than 66-440. Not sure what the difference is?

66 440 is the M20 M21 part.

The B33 part takes 1 roller bearing on the gearside.

The M20 M21 takes 1 roller bearing and 1 ball bearing on the gearside

I had a timing side shaft made at Autocycle Engineering to the pattern of the old damaged one back in 2012. They also fitted it to the flywheel and rivetted it. They may still have the drawing?
