Is the Allegro not the one with the horizontal oil filter screwed directly to the block?
Not that I recall, not even the 998's!
The inline version used in the Marina did though

I think the Maestro 1300 had a MPi style filter arrangement.

While there were many different castings over the years, it is one of the Automotive Industries remarkable engines. If memory serves, it was first on the drawing board either just before or during the war, eventually going in to production in 1951, went through a few transformations, in particular in it's later years to meet ever stricter and more difficult emission requirements, of different types for different markets, and lasted until 2000 - all the way on a Cast Iron Head, for the most part, the layout was also unchanged. There'd only be few such engines from any manufacturer that would equal or better this.
The more I look in to various design feature of the engine, it's layout and keeping in mind that it had to be a mass production engine for passenger cars the Austin people who did the original design work really knew their stuff well and did an incredible job.
I don't think there's a listing as such compiled, but the book written by Graham Robson - ' The A Series Engine, it;s First 60 Years ' is a great and informative read. Do a search on the Forum, mab01uk has posted some extracts from it.

In terms of different casting's it depends how far you want to dig, as there are different castings for the same series block, for ecample the early 1100 blocks couldnt be bored as much as the later ones, also theres two wfm1024 A+ blocks ( or more) below is a list of some block numbers,

In addition to this there are a couple of Pre A+ block, as some have a hole above the centre main bearing and were allegenly weaker.
ttheres also the south african 1100 blocks which along with the Maestro blocks have the filer up top look like an MPI one bit wih a dizzy hole.
Ive wondered if the innocenti's used different castings.

I think most Innos used UK supplied engines, Authi did their own engines and South Africa and Australia had a mix of UK and their own.Ive wondered if the Innocenti's used different castings.
