The ME2 was introduced in 1958 at the same time as the ME1. Dimensions of this engine are the same as the ME3, except that it had a Mamod upright engine as opposed to the SEL upright engine used in the ME3. The ME2 was not particularly successful and was replaced by the ME3 in 1965. The fact that the ME1 represented a complete engine unit, whilst the ME2 basically was the boiler and engine unit probably worked against their success.
