    Another possibility – the Fiat numbering convention isn’t the same as Hamilton Standard’s, and the ‘-30’ doesn’t mean 30 in/cm reduction at all.

    In which case a 9′ 6″ prop, if Hamilton-based would almost certainly be modelled on the standard and fairly common 9′ 6″ 3D40 – type blade family 6181, 6381, 6095, 6167 and 6237- figures below:

    Can you confirm the prop diameter? Hamilton didn’t make any 10′ 6″ D-shank prop assemblies. Neither did they make 12′ ones, which it would be if the ‘-30’ was in inches.

    However, I got the 9′ 6″ from Wikipedia. 9′ 9″, for example, would give us some very good candidates, such as the 6127.

    ..so I reckon the 5010 was the Fiat choice for Merlin applications and was modelled on the HS 6xxx as per the P-51, which means that we only need the Hamilton model suitable for A.74 (?) applications that Fiat chose and called the 5101. The -30 might be the clue – as the CR-42 had a 9′ 6″ prop diameter I need to find something in the right power and RPM range that is 10′ 6″ (30 cm – ie 12 inches – greater) in diameter ‘uncut’. Already I have an idea – I need to rummage.

    Thanks for the update, Paul. Bated breath!

    OK – either:

    An early 1930’s US Navy design (just going by sequential drawing numbers),

    A typo for 5010 – the Fiat Aviazione manufactured Hamilton-style blade made for Italian Merlin applications – such as the G-59

    A typo for 6101

    Apart from that, can’t really find anything in that range – presuming this a Hamilton prop? One thing to note is that none of the 5,000 series – mostly Navy designs – were for controllable-pitch hubs. If that is what you are looking at then 5xxx is not the blade number.

    I am interested in what it is you have come across

    Cheers,

    Matt

    ZRX, I get the impression that a lot of what became Lockheed’s ‘history’ was put together at the time by their PR department. That statement is interesting!

    Thanks alertken!

    Yes, Addams didn’t buy – or even formerly accept – anything. But he is pictured in the US press shaking hands after test flights, climbing out of cockpits in his tweeds etc – he was the presence on the ground, representing the ministry if not actually being it. He was asked to test the Hudson pre-order, and it appears he had a similar role with the Harvard as well, from a North American Aviation in-house magazine report of the time. I am sure there were other personalities attached to other manufacturers – Addam’s ‘patch’ was California – Lockheed, NAA, Vought (he was all over the press testing a Vanguard) and Consolidated (he was expected – again according to an in-house magazine – to have travelled on the first Model 28 (Catalina) to cross the Atlantic, but I can’t find out whether he did or not).

    So no overall say, but much more glamour!

    Back briefly to the black/white undersides thing – it is indeed a timeframe issue. Firebird mentioned 257 having black/white in November 1940 – this was due to a fresh order from Fighter Command to do this in November, which lasted until March 41. The previous spate of doing this was officially ended – off the top of my head – on June 7th 1940, though I’m sure it wasn’t instantaneous ‘on the ground’.

    Yes, it seems Addams was ‘the man on the ground’ on the West Coast, ultimately reporting to the Air Ministry, perhaps via Marsden?

    The LA gossip columns recorded every week what parties Addams had gone to and with whom, between 1939 and his marriage in 1942. It seemed LA high society was fascinated by him. Apparently he and Bob Gross, Chairman of Lockheed, would talk about aeroplanes all night. Not sure how that works in terms of impartiality – but I reckon there’d have been quite a falling out when the Ministry refused the P-38’s being built for them at great expense – possibly due to his flight test report. Maybe the ‘talk’ was in fact negotiation.

    Regarding his judgement, it would seem that the several various references to rejection after testing by ‘RAF pilots in the US’ or ‘A British evaluation pilot in Burbank’ (Bodie) of the P-38 model 322-B without the turbo-superchargers and with mach-tuck and ‘flutter’ issues are probably down to Addams, though these pilots are never named. He was embedded into Lockheed at the time, though I imagine his position could probably be seen as quite awkward in situations such as this.

    Thanks Bazv!!

    I’ve been digging as well. He was the son of two well-known artists, Clifford Addams and Inez Bate. His dad abandoned his family citing ‘cruelty’ on the part of Inez. His younger brother died performing aerobatics in a Siskin in 1926, and in his memory Inez instituted a trophy for an annual 41 squadron aerobatic contest. Different times. His wife died in 1936, leaving one daughter Victoria Dawn, who went on to fame as the actress Dawn Addams, and then married an Italian prince. In LA, and while mixing with stars (Douglas Fairbanks Junior was a close friend) Addams married actress Aline Judge – one of seven of Judge’s marriages.

    When he was posted back to the UK (To Milfield, where he was reputedly the only owner in the RAF of a tailored battledress) she divorced him for ‘desertion’ after shacking up with a Chicago ad man (victim number four). After the war he moved to Italy – somehow ending up in 1960 with the speaking part of ‘Corrado’ in the new-wave Antonioni film ‘L’Avventura’. It seems the film world is unaware that this part was, rather curiously, given to a retired RAF Group Captain rather than a professional actor. This was the only film role I can find, though he was senior advisor on ‘A Yank in the RAF’ back in 1941. So an exciting life generally.

    Edit.. yep, definitely the same chap: [ATTACH=CONFIG]258677[/ATTACH]

    The thing about the US neutrality acts is they only applied to ‘belligerent nations’, and that didn’t include the UK in 1938. Ironically it was only in September 1939 that the UK became unable to rely on the US for arms purchases.

    Bolton-Paul made and installed the turrets in the UK – it made sense to do it that way, due to the weight.

    I’ll look for other pictures of this aircraft – it featured heavily in the press at the time.

    Thanks for that anyway, A.M. That is one fat file!
