Another picture of the AEC that Oily posted on Monday. I had a bit of a search
and I found that it has a petrol engine of about 9600 cc, Would that have been
an AEC engine, or perhaps from another engine manufacturer ■■
The Mills AEC Mammoth Major Eight in the pic dates its registration from October 1934 to September 1935 Liverpool, the AEC eight wheel rigid was the first to be produced with an Internal Combustion engine and this was in 1934, although AEC had developed the ‘Oil Engine’ in 1928 being put into vehicles in 1930. An 8.1 litre engine that by 1934 was developed into an Indirect Injection 8.8 litre of 130bhp @ 2400rpm, quite an achievement in power at that date. However some of the first MM Eights were fitted with Petrol engines so it’s quite likely this one in the photo was one of those and it would have been an AEC engine. I believe this vehicle is preserved in a Museum. Franky
