Hi Martin, I see you found the link to my partly completed drawing of the Boomerang dimensions showing the fuselage frame position: http://www.buckmasterfamily.id.au/plans_pdf/CAC_Boomerang_plate_1c.pdf This drawing is still not finished, and details of the framework tubes are one of the...

My "DB Design Bureau" website on my family web domain has not been updated or touched for about 10 years. Consequently, it doesn't have any of the latest security protocols coded into the HTML, so some browsers may give you a warning even if there is not a problem. I've been slowly moving all...

Hi, can anyone help with dimensions for these tanks? These were the standard pressed-metal tanks carried by Mustangs during the 2nd World War, with a welded seam around the centre of the tank where the 2 halves were joined. I have many 3-view drawings showing these tanks, but none showing...

For the Wirraway fans, I've just added a set of drawings for the CA-1 Wirraway, showing lots of detail. As far as I know, this is the first time the CA-1 (as it rolled out of the factory) has been presented in detail for a 3-view drawing. There are some Wirraway drawings floating around, but...

Can anyone help with more details on the parachute supply containers shown in the photos below? These were used by the RAAF in New Guinea, and known as "Jungle Type Containers", but I think they were fairly common. I'm specifically looking for dimensions. Note that these...

Great, thanks everyone for the tips. I have what I need now, puzzle solved! :-)

OK, a strong candidate: Bomb, Practice 100-LBS, Mk 1. http://www.nao.usace.army.mil/Library/Factsheets/PlumTree_Island/Documents/PTI%20ASR%20Supplemental,%20Munitions%20Data.pdf Looks streamlined and with long angled fins.

Excellent, thanks for the help... I'll go hunting in those other threads.

I was thinking they would be practice bombs also, but they look much larger. Does anyone have a reference for US bombs in the late 1930's?

On Flikr there are several photos of the North American NA-16-2K from San Diego Air Space Museum showing the aircraft in California before it was delivered to CAC in Australia: North American : NA-16-2K AKA NA-33 | Flickr - Photo Sharing! Can anyone tell me what size of bombs are...

Hi All, I just added a cutaway drawing to the Wirraway technical information page (link in the first post above). It was drawn by F.D. Rogers in 1944, so it's not super-high quality. But interesting nonetheless. Cheers, Derek

Hi Bitis, did you ever receive a response to your request? I'm looking for the same thing. Regards, Derek

Glenn, in essence, from the design point of view the Boomerang is exactly as you have described, it's a Wirraway airframe with a more powerful engine, no rear seat, modified rear canopy / rear fuselage and increased armament. In addition to this it has shorter wings (faster roll rate) and a...

Hi all, while I've been doing research for my drawings of the Wirraway and Boomerang, I've collected a bunch of interesting information (well, I think its interesting, anyway). I've decided to load some of it to my website, so others can enjoy (?!?) this esoteric technical stuff... Click...

OK, I was able to join AEHS and they have been very helpful. I now have the dimensions I need... Regards, Derek
