    I don’t care – where do I send the cheque!

    Almost definately – people made and sold anything in the immediate aftermath just to eat, and I would imagine that a box of surplus pistons and a plentiful supply of trophy hunting GI’s may have made a good business model. More likely a managers desk ornament or something for the boardroom.

    Just a thought..

    Been cogitating over the numbers, and the only idea I can come up with is they might be the size and weight category.

    In mass production everything is almost the same but it’s best to match the bore as closely as possible so for example an engine with one bore in the ‘8’ size range is matched with a piston of the same range. Each bore could be different. These variances will be small (100ths of a mm) but help to maximise power and reliability. The second step is the weight so that all the pistons have a similar mass – again the deviation is small – con-rods are also matched by mass. Result is less vibration and better reliability.

    Sorry that got a bit long winded 🙂

    I think a lot of kanji has fallen into disuse since the war due to it’s relative lack of flexibility. A lot of westernised terms are used – Brake becomes Buraku for example, where there isn’t a relevant or convenient Kanji or Japanese word available.

    Add in the joy of Hiragana (for traditional Japanese phonetics) and Katakana (for westernised phonetics) and it’s little wonder it gets confused! Many younger people are using less Kanji in preference for Hiragana, hence the term “Old Kanji” as some characters fall out of regular use.

    The Hasagawa one is beautiful – I’ve lusted lustfully after that for long long time! It was one of the reasons I ended up with the Alby because it was available (got it cheap from Ebay) and the SE wasn’t.

    I think the earlier posts saying that it’s some kind of award for collecting metal or similar for the war industry is spot on.

    I’ll ask our Nihongo Sensai next time she is in the office – if anyone will know the mystery Kanji she will!

    Hasagawa used to do a marvellous Se5a but that falls into the complicated category! I think Eduard do a range of 1/48 and maybe 1/32 WW1 models.

    I have the Model Airways Albatros DV to make but I will have to wait a bit to start I think.

    I for one am very dissappointed as I (well my in UK residence) live about 3 miles away from the current base! Have very happy memories of D checking G AMPY with Dave Kingshot and the crew + helping out Netty on the open days.

    Guess it’s I’ll be approaching Brunters, MAM or the Shack team for volunteer duties (actually Richw 82 PM me if you want a spanner savvy helper! Back in October)

    I’m going with Anon then, a crankcase fairing for a radial.

    What are they on/from?

    The left one says something like train for a better/stronger spirit or body, and the second denotes “organise”.

    Old kanji again apparently (my friend says).

    Hope this helps 🙂

    What’s the diameter?

    Your car (if it is under 20 years old) will be EMC tested to 30 volts/meter over 20mHz to 2GHz in a similar way to above. An EMP is estimated to be in the region of 50 – 100 V/m. Having said that I’ve not seen a vehicle fail in 9 years of testing. I’ve seen the cameras in the lab have serious wobblies if the Faraday cage is not grounded properly though.

    The spikes are there to absorb the RF energy that would reflect off the walls. As the antenna emitting the energy is directional anything reflected off the floor will be absorbed in the anechoic cladding. These places are called Semi-anechoic chambers and are weird to be in as there is no echo and all the noise is deadened!

    A second opinion.

    According to my Japanese friend it says:

    Yakudutsu Hitoni – We want or aim to help (accross the wing)

    Either Okua or Ohmori Kodomo Kai (the second kanji is definatly a little old) down the fusalage, and this is a Childrens Council or Society in Okua/Ohmori.

    So that confirms mhuxt’s top line with now 3 possible locations for the fusalage!

    As for the logo she thinks its a location again – like a district badge with the star denoting an award of some type. She initially thought it was the same as the 2nd kanji down. Certain that it isn’t Nakajima/Kawasaki/Mitsubishi.

    Don’t worry about kanji being repeated – two kanji together often have an entirely different meaning to a single one. The main reason that I gave up trying to read Japanese!

    Oh and give me a Japanese girl over a western girl any day!! One of the reasons that there will be fingernail marks all the way to the aircraft seat when they drag me back to Blighty in a month (after 4 years).
