1275 Engine

[Lancer7676@aol.com]

I pulled the head off the 1275 I just bought with a parts car.  I was
wondering if anyone could tell me anything about the engine from some numbers
I copied.  The engine is super dirty inside but will turn over.

On the tops of the pistons is the following:

                  B
     M2213        9

Do these numbers mean anything?  Is this a standard bored engine?

And on the head is the following:

            12G1316

The car is a 1973 Midget.  Thanks for any input.
