wayward, it was an observation not a question.
And I observed the fact that there are two different types of screws in the lid portion of the hinge.
And I observed the fact that given the extent of the rusting of the upper portion of the hinge there is basically little to none of your per say “spider webbing into the wood” of the lid, ….. a fact that I find hard to believe …… given the fact that the lower portion of the hinge is considerably less rusty but there is obviously a greater amount of your per say “spider webbing into the wood” of the back board.
wayward, extensive rusting = minimal bleeding ……. verses …… minimal rusting = extensive bleeding, …….. makes no sense to me ……… unless the top board/lid has been replaced, ….. which would support your claim of it being made out of pine. And the way the hinge is made it has obviously not been turned around.
Now the side boards of that box looks to me like they are 4-quarter, which would be what one would expect to see for something that was made sometime in the 1800s, ….. but the question is, ….. is the top board/lid also a 4-quarter board? If not, then pretty much for sure, it has been replaced, ….. because the tops of dough boxes were used as a “work surface”.
wayward, I have at this very minute, lying on my carpenters bench in the garage, three (3) 4-quarter by approximately 29” X 50” popular boards, that were salvaged from the base unit of a large 2-piece cabinet/cupboard, anyone of which could be used to put a lid on that “dough box”, ….. which is for such a reason I have been saving them for more than 20 years …. and the fact that these size boards are scarce as hen’s teeth because they were cut out of “virgin timber”.
I just took a photo of them because a picture is worth 1,000 words. The one on top, with the 48” plastic straight edge lying on it, was the top of the base unit, the other 2 were the side boards of the base unit.
