Hypersonic Models has posted images of the test build of the injected plastic 1/48 scale AG-330 start cart that was developed for the Lockheed SR-71’s J58 Pratt and Whitney engines

”A few more pics of the now completed test shot build of the AG-330 (Buick variant) with PE. The plastic parts are pretty good already, some of the PE parts need a bit of a design tweak as they were too small to bend properly on places. Watch this space...

You can build both the early Buick Nailhead and the later Chevy versions from the kit. The gear probe can be built extended as well (height to match my SR-71 kit of course, adjustments may be necessary for other kits).”
