Incomplete Mark / Mountain with A and M

[SwissSilverBuff]

I can't seem to find this one in the catalogues.

It is incomplete but has a clear A and M on either side of the mountain. To the left of the peak there appears to be a number 5. It is not easily discernable as a 5 in this photo but with a good magnifying glass and some twisting and turning it is most likely a number 5. What the mark to the right of the peak is I can't tell. It is a small silver plater which has a rather thick base.

Thanks for any input you might have.

Hi

das gseet ganz fescht wie vörsöuberet uus... :-)

this mark looks VERY much like a mark for silverplated items.
Then AM would be the marker and the 5 most probably indicate, how much silver was used to plate the item, here 5 gramms.
Are there no other marks?

Kind regards

:) Merci vielmals...

Unfortunately no other marks. I have checked it out thoroughly.

What is unusual about it is that the base is unusually thick making the whole thing a bit heavier that you might expect by looking at it. So there might be some heavier base metal in there. The weight makes it slightly harder to slide on a table which is practice when you use it as a platter for a glass for example.

I see absolutely no dull spots you often see in thin silverplated platters in the areas where you would expect some wear.

It also rings fairly long when struck firmly. I have heard various things about the "ring test" but most of my silber pieces either have a dull or short ring when struck firmly.

I'm now guessing silverplated but would love to know from which maker. It is a very nicely done piece with a very classic pattern around the edge.
