However assuming that the image originally posted was upside down, the maker's mark would be a 'W' and not an 'M',as both symbols contrast and maker with be in the same position. My book on contrasts and makers marks was published in 1958; i can check marks since the 15th century to until 1950, but the objects under discussion were visibly made on a later date; the original Eagle hallmarks only contemplated touches from 833 up to 916; no 835,which was part of my riddle. Apparently for the same reason i don't find in the book any makers mark, be it 'M' or 'W', with such design.Traintime wrote: ↑Wed May 03, 2023 7:41 am The implied maker’s mark would seem to be “M-under-an object” (or “M-surrounded by-an object”). [One thread points out that the letter may be a first name rather than a last name..we’d have to confirm this practice…for later makers at least.] The question, besides whom, would seem to be is this consistent with late or modern Portuguese maker mark practices?
Not pretending to complicate things, but the Portuguese authorities have since then issued newer regulations. Looks like the 835/1000 Eagle fineness is now ... a rabit.Traintime wrote: ↑Wed May 03, 2023 7:00 am Chart for modern Portuguese: https://www.925-1000.com/Fportugal.html
Right facing would likely be .835 (835/1000) fineness here.
