Before I attended this discussion, the mark was discussed with some of my friends (Finns, but not dilettantes). We all totally agreed that the mark is not from Turku (note the spelling!). Then I provided Oel with the link he showed on 24.6. at 2:52. All Turku town marks are clearly visible on the site. None of them resembles your mark close enough. Did you even check the link? In case you didn't here it is again: https://www.leimat.fi/en/localitymarks/ ... -t-z/turku
. Please, take a look.
Now additional material has been provided by Sasropakis (also a Finn) and Oel. All talking against the mark being Finnish. Moreover, I didn't expect anybody to demand a whole novel written by me or anybody telling that the mark is not Finnish. I thought my word would be enough but it wasn't for you. I am respectful, how about you? Anyway, more evidences have been showed. I hope you are you satisfied now?
Now please check the the French connection; Angers 1747. You will find a very similar mark in English Tardy on page 142. France has been mentioned in several inputs. Most likely your piece is of French origin. Also the geography talks for that.
