[allisland14]

hello, i am new to this forum but have been using this website for years to help me date and find out manufacturers based on just images! this website has been my go to! lol. ANY HELP WILL BE GREATLY APPRECIATED!!

today i came across some older silverware pieces that have some hallmarks i was unable to find on the website (maybe i am just blind and did not find them) but from what i can tell from my research is that they are either from : Portugal, Netherlands, Denmark or Norway?

the hallmarks and stamps appear to be a waning crescent moon, a lantern, a arm or sword, and "833" silver purity.

i will attach some pictures and the link to the image gallery https://postimg.cc/gallery/sDb1NhY
