Taking into account the age of the Merlin design and its relative small displacement this two-stage inter- and after-cooled engine was a superb machine. In comparison with the German engines the Merlin was lighter due to the relative abundance of metals for making light alloys. When comparing outputs one should also bear in mind that the allies were well supplied with high grade fuels (100/130/150 octane). The Germans had to make do with 87, 92 or 96 octane, the higher grade fuels being especially scarce. ADI was used by both sides in the later stages of the war.
The Merlin 60 series were put into service in the late summer of 1942, around the same time that the DB 605A-1 went into service. The high altitude performance the Merlin 60 series was superior to the DB 605A-1. This superiority lasted into 1944 when the new AS and D sub-types went into service. These late sub-types equalled or bested the high altitude performance of the Merlins (Rolls-Royce and Packard) perhaps with the exception of the Mark 70. When GM-1 was used the picture changed thoroughly in favour of the DB 605.
The DB 605 basicallly gave good low altitude performance, especially at sea level (read the discussion of the supercharging systems). In this regard the DB 605A-1 was superior to the Mark 61, 63, 66 and 68 Merlins. The superiority of the late mark DB 605's at low and medium altitude was very pronounced when using MW-50 (AM, ASM), high octane and high boost (DB, ASB), high octane high boost

There's a classic working warbird museum in west Cornwall I've heard. Must go. Can't remember where it is though.

Absolutely correct........they are simply stunning and as you say, as far as proportions go, can't fault it.

Yes, not far from our Fowey base......just never have followed it up. Once we get to Fowey, the driving's over usually. Will have to go those few extra miles this weekend.
And re proportions..........the Mosquito has a lot of competition.

Don't think anybody has ever seen one flying.
