English vs. French Dovetails
I am not a woodworker; I'm doing a little historical research. In the incident I am curious about, one person looked at a box made 100 years ago or more, and concluded it was made in France while someone else concluded it was English. My limited reading on dovetails so far, I've found that the full blind dovetails are sometimes also referred to as french dovetails. One source I came across says that as a rule of thumb comparing English, French, and German dovetailed joints English dovetails are the skinniest, German dovetails the largest, and French dovetails are somewhere in between.
So my question is, do certain types of dovetails, as a general but not infallible rule, indicate a certain country of origin in antique (100+ year old) woodwork?
Thanks to all for tolerating what is probably a very naive or unanswerable question (we all have to start somewhere).
