Sunderland I v III nacelles

[dalea]

Is there any noticeable difference between the engine  nacelles of these 2 marks? Thinking of tinkering with the Airfix MK. III. Got lots of aftermarket for the Italeri Mk. I.

The Sunderland Mk I had the Pegasus Mk XXII engine, and the

Sunderland Mk III had the Pegasus Mk XVIII engine.

If you compare the chart in link below both the Peggie 22 and Peggie 18

had a similar radius (55.3 inches) so in respect to your question the answer

would be no.

Caveat though, is that the Mk I had the inner port exhaust which differed in that

the exhaust went through the wing leading edge, through an internally mounted

water filled heating chamber/boiler, which provide hot air for crew warmth.

You can see the exhaust running along the side of the Cowling as opposed to along

the upper cowling in this IWM Photo

Hope that helps?

Yes, thank you. Was aware of the port inner.
