Many thanks

Thanks to all for your replies – all now clearer.

Are the photos shown in the posts from Morgan and Shacklady book? I don’t have that in my collection, and I haven’t seen most of these.

Thanks again.

Regards, John

Peters notes make perfect sense; there is no provision for an oil filler in the cowling shown in that picture, so it must have been the earliest case of moving the oil tank to the fuel bay.

Ah – that would probably be it. I see this is referred to in the documentation on the Mk XIV, but is not referenced on the Mk III documentation.

It now makes sense – simpler to retain the oil tank provision as it was on the Merlin variants, but with the different engine mounts on the Griffon variants, use the method trialled on the MK III.

Many thanks

The enlarged main fuel tank on the Mk.VII/VIII was achieved by deepening the tank, at the cost of additional maintenance time and difficulty. It does seem a shame that this never made it to the main production lines, but again this would only have come at the cost of reduced production during the changeover.

Thanks for this – so not then a forward extension of the fuel tank

There is infos about the Mk.III in the latest issue of The Aviation Historian with profiles by Juanita Franzi.

Yes, thanks.

That was, in part, what prompted the question, which was an old query of mine. I have asked TAH if they have any more information.

Spooky!

My history is similar – never a Flypast (FP) reader, AE Quarterly (AEQ) died, I gave up on Air International (AI) a few years ago when it became (IMO) a ‘trade mag’ monthly equivalent to Flight, and now AM and FP are in the same stable – it remains to be seen what happens to both titles. I’ll review when my sub to AM expires.

In the meantime I have decamped to ‘The Aviation Historian’, run by a former editor of AM, as a replacement for AEQ

But I do wish something like the old ‘AI’ – paper and/or electronic – with a mix of historic and current could be revived. The railway mags can do that – why not aviation?
