Kerrie Dougherty (formerly of the Powerhouse Museum) has written multiple papers (see: https://www.oldrocketforum.com/showthread.php?t=14824 ) on Australian-developed (and non-Australian, but Australian-used) sounding rockets, re-entry test rockets, hypersonic test rockets, and satellite launch vehicles that have been flown at Woomera. She used all-SI (metric) dimensions, but I was able to identify several vehicles, mostly Australian-made, whose development and/or use pre-dated (or spanned) Australia's conversion to SI, which--if memory serves--began in 1971. For example, I would come across a fin dimension (its chord, say) of 152.4 mm, which is exactly 6" (6 inches); 125 mm (the diameter of the Zuni unguided air-to-air/air-to-ground rocket) is exactly 5", and so on. If health permitted (unfortunately, it no longer does... :-( ), I would love to visit Oz again, and see the Woomera museum and "wild" displays, BUT: If you--and perhaps also a friend or two (to confirm paint scheme colors, at the very least)--visited Woomera and photographed & measured the vehicles (after making sure it would be open, beforehand), there is a treasure trove of scale data there, just waiting to be recorded. If you brought along--and/or e-mailed them scans from it, beforehand--a copy of Peter Alway's book "Rockets of the World" (or one of its annual supplements), the folks at Woomera would have no doubt that you were a serious researcher, which would "open doors to you" that aren't open to the average tourist. As well: Few Australian sounding rockets are well-documented, in terms of scale modeling data or missions history. Only the Aero-High and HAD (High Altitude Density) are in the 1992 Edition of "Rockets of the World," if memory serves. He also covered the Long Tom in one of the annual supplements, but it was the last-ever round to fly, which--while perfectly fine as a scale model subject--was not typical of the type (it had different fins on both stages than did the previous Long Tom rockets). Besides these, ^here^ (see: https://space.skyrocket.de/director...r_australia.htm ) is a list of Australian sounding rockets that have *NOT* been documented (and here is a longer such list, with descriptions: https://www.oldrocketforum.com/atta...achmentid=40105 ), but which are "available for inspection" at Woomera; they are: [1] HAT (High Altitude Temperature [it used the same LAPSTAR second stage as the HAD, but boosted by twin Demon motors, instead of the HAD's single Gosling first-stage motor]); [2] Cockatoo (this was the HAD's replacement, which began flying after the WRESAT satellite launch in 1967--like the HAD, most Cockatoos boosted 2 meter diameter, inflatable aluminized Mylar "falling spheres," which were tracked by radar to garner edge-of-space wind data); [3] Aeolus (it used a standard Long Tom second stage, boosted by a seven-motor [LAPSTAR] first stage); [4] HAEC (a once-classified Australian sounding rocket); [5] Lorikeet; [6] Corella, and: [7] Kookaburra You could POD (Print-On-Demand) publish the scale and historical data, at zero cost, through Lulu.com (www.lulu.com - I use them; see below) or CreateSpace.com (www.createspace.com ).

You're overthinking this my friend. I just read the label :-)
My color vision disorder is mild (very few people are completely color blind) and affects mid frequency cones. Not as sensitive to green and overly sensitive to red compared to 'normal'. So some colors just look different to me and I long ago gave up identifying things by color. re Woomera and Oz sounding rockets As I mentoined in the other thread, I live in Boston, so popping over to Woomera isn't an option for several years at least. I do have dimensioned drawings of several Oz sounding rockets, including 4 of the rockets you mentioned (HAT, Aeolus, Cockatoo and Kookaburra). I'll post some details in the on-topic thread. The main public cutover to metric was 73 IIRC (at least that is when the speed limits changed). Everything in school was metric from th late 60s so we could forget about about rods, perches and chains. All of those rockets would have been built to imperial measurements. gary |
