crown on top of N

Looks like a modern day Capodimonte. I cannot make out the name under the N, but that is likely who finished it. It has a model number impressed off to the side. Try searching for Capodimonte and that name.

may be a continental 7 as the last number

I have a piece with a crowned N too.
It has some amateur repairs but has a very old look and feel.
Don't have a clue about the mark, sorry.

There was a German factory in Sandizell, Baveria called Hofner & Co. that used N and a crown but the crown was not the same as this.

That factory started in 1951 and there isn't a factory from an earlier period in the most significant European Porcelain Marks book with N and a crown closely resembling either of these.

the name under the N, looks like SHarder, I've typed in varients of the name but have come up blanks, any ideas ??

Could it be Schrader?
