looking to ID 1100 engine

Have an old 1100 (?) engine I was looking to find the vintage and specs for. It has the fuel pump side mounted and generator stand cast into case.

The number stamped near the generator is 1-1,133,298

I found this resource

which tells me it could be a 1947 25 hp, but my # is slightly larger than the max engine number listed for 1947. It appears starting in

1948 the engine numbering pattern changed and no longer starts with the 1- like mine does.

If I ignore the 1- in my number, the serial 1,133,298 puts it as a

1955 36 hp.

Any ideas?

I'm looking at Bob Wilson's 1949-1959 VW Beetle book, an authoritative source.

The last engine number in 1948 was 122,649.

Your number 1,133,298 places it during the month of February 1956. (The last engine # in February was 1,344,312.)

But what's up with the 1- in my engine number? From the above resource, it shows all engines 1947 and prior had the 1-, numbers after 1948 did not have the 1-.

Is it understood that you just drop the 1- and assume it is a later engine/number?

Is there any other way (besides measuring bore/stroke) to tell if it's a 1100 vs. a 1200?

1947 (1 Jan 47 - 31 Dec 47) Engine: 1-090,733 - 1-0100,788 1948 (1 Jan 48 to 31 Dec 48) Engine: 100,789 - 122,649

The intake manifold should be different between the 25 and 30ps engine. Also note that the -56 engine is a 30ps engine, only referred to as a 36hp (SAE) in the U.S.
