If a member has J 3097 and is not already aware, what seems to be the block from the factory fitted replacement engine still exists and currently faces the prospect of being fitted into an OHC Minor with the addition of an OHC Minor cylinder head.
It is marked 2/1922 CJ J72 (so far as I can tell from the blurred picture below).
It seems to be a replacement although I would have expected to read the number 1577 C J .

J3097 is listed in the Register, Registration number ALM24, engine number 235AJ and the early Triple-M Register number 340.
However, it appears we have not had any information on this car for a long time. The unconfirmed information shows J T Webberley as owner.

Sam,
Perhaps this is the original block which was replaced by 1577 and it was recycled and fitted as a service replacement to another car at a later date?

I wonder about the engine number taking the form of 2/1922 with the number '2' prefixing the proper engine number. As you suggest Simon the '2' could relate to it being the original block recycled in 1936 and the extra digit added.
It seems odd though that the position of 1922 leaves plenty of room for the addition of '2/' . Those blurred letters 'CJ' might suggest something when the file says the original engine was an 'AJ'.

On my P-type I have something similar wrt the engine number. My original engine has number 1136 AP, see attached picture. It has a crack at the water compartment, in time I might get it fixed, but for now I have the engine rebuilt that was put in the car by the previous owner in the sixties.
The engine second engine has number 2/1134 CP. '2/' shows it has been refurbished by the official MG service, and the CP stands for an overbore for the cylinders, +0.060 from the top of my head.
Currently I have the original engine of PA0881 in my car, while my chassis is PA0884, a fun side-note  .

****CJ and ****CP denotes that the block for these J and P engines may have been overhauled at the Works and rebored. The suffix 'B' indicates 0.010" oversize and 'C' denotes 0.020" oversize. (The standard blocks would have been numbered ****AP and so on)
Is it my eyesight or are the stampings on Sam's 1922 numbered block a bit smaller than 'original'?

If the current owner had mastered the macro facility on his camera the numbers would have been much easier to read.
It does look as though the engine numbers are smaller (although the J 72 seems the normal size). Perhaps the factory stamped the engine number on 28th January 1936 (as noted in the ledger) and did not think to use the punches from nearly three years earlier.

I notice ALM 24 is still listed by the DVLA (according to National Tyres).

That's odd, because the Register records suggest that a car bearing that reg is in the USA with one William Goulette! Maybe the mark has been transferred to a completely different car?

Dick MG sometimes used the smaller stamp size. I have seen both blocks and chassis knuckles stamped with the smaller size.
