With this whole line of inquiry I am in the awkward situation of asking a question which I am not certain has an answer. In fact the further I look, the more I suspect I cannot definitively narrow the date range on form alone past late 15th-early 18th centuries.

But the worst that happens is that no one else has an answer either, I keep the wider date range, and nothing is lost by the attempt.
