Geez, Sam, that is awful nice to just flip, not being broken, and all. No room to stash it in a pile somewhere, eh? JK - good luck with the profit!
Sasquatch - great find!
Lug - the RJ label is black with gold letters. I think I may be able to get it onto a flatbed scanner, which may be better than a photo. There are actually a few of these boxes on eBay, and there seems to be two variations on the black label. One has a prominent "To the Public" notice. Also, the hinges may indicate age. The full strap style I think may be younger since it continues into the Stanley era, and separate smaller hinges may indicate older examples - not sure. I know you've said you don't purchase on eBay, but some have labels that are more intact than mine, so wherever of mine may be illegible, there is a resource for filling in the missing information.
I saw there's several Stanley ones, and looking closer, I think that wood is poplar, not birch. I think the machined parts that cradle the bits are probably basswood, even in the older ones. One eBay example sure looked contemporary with mine, but despite the cut-and-paste description the vendor was touting, it was definitely not oak, but probably poplar with a dark stain on the exterior. From glancing at the text on the label, maybe they always used various hardwoods, and there is no chronological progression in materials.
Also, thank you very much for the exposition of the shadow sheet. When I saw it, I was pinched for cash and time, so I just took a couple photos. It is cool, and I suppose if I see another, I'll have to have it.
