There are a couple of other options that could work;
IF what you need are the actual shapes / sizes of the individual hull schurzen plates, getting someone to photograph a sprue of kit parts from a Dragon 1/35 kit or a PE plate set, with a metric ruler placed along the side, would allow you to scale the image and get / create a matching set in both shape and size from sheet styrene or ...
IF what you seek includes details of the mount racks... photos of sprue parts with ruler could help there, too - likewise scaled photos of a PE set with mount frames could be useful.
In all cases, I would back up my diagram, part / sprue, or PE-based form and size info with a good look at several photos of the real things... These real photos will clarify visible details and thickness appearance (PS: styrene mount frames tend to be too thick, but often mostly of the right general form and shape, while PE frame parts are almost guaranteed to be substantially too thin for most of this stuff.) and help you get what you are looking for.
Cheers!
