Engine numbers

[Gibbo]

Hi Can anyone please tell me the year and info on engine number M256468.

[Paul Cooper]

According to Wyatt it around the end of October 1936

Further note, it should be a three bearing engine given the date

["Slack Alice" Simon]

It is probably a 3 bearing engine, from around October 1936.

If so, there should be the head of a bolt high up on the crankcase side, half way along, just below the tappet cover.

It may have been modified the take a 2 bearing crank, though.   I don't know if this can be checked by looking down the oil filler tube.

If 3 bearing, and the engine came from, or is still in a car that hasn't run for years and years, the crank is probably broken.

They will often turn over on the handle, even with a broken crank.

If it has obviously been looked after, then a good three bearing engine is a much smoother driving experience.
