The shocking thing is that indeed yes, the stitching does go right through the plywood case. My main question in seeing that is whether the holes were predrilled or was it just one hell of a sewing machine? I’m inclined to believe the latter, but if I should ever want to make something similar I will be doing the former, though realistically, this does not do the the concept of ‘watertight’ (or even resistant) any good.

Note all the stitching rows right through. If this had been hand made, given all the material I’ve read, I would expect some of the stitching at the corners to go from leather to leather outside of the corner, but not here… It seem to conflict with Stohlman’s ideology anyway.

The interior parts are interesting though. the pieces were backed by a lightweight chip-board except at the hinge where the fabric was adhered to a flexible plastic material. again, the stitching was straight through the cardboard, but I guess after plywood, what’s a bit of compressed fiber? The board is only used on the panels that have something else sewn to them. sort of like a heavy duty interfacing.

Given the heavy industrial aspect of the case’s construction, there’s not a lot of information for the budding hand maker, but there’s a bit to go on. The plywood form is interesting. A reminder that like upholstery, the construction of the underlying form is rarely available for criticism.
