Hi, @davejones, it's a lovely piece!🤗
It's difficult to say who, when or where was made this fruit bowl, I can only guess.
My thoughts:
1. It's not italian made. 900 standard of silver was never used in Italy. Actually, entire Europe never used 900 silver, the only exception was Bohemia, but they used the austro-hungarian hallmarking system, so definitely it's totally different
2. Another countries where was very popular silver 900 in flatware and holloware are Egypt and Turkey (ottoman empire), but their hallmarks are very easy to identify and the ornaments on your piece are for sure not oriental.
3. Although silver 900 was used in many south-american countries (Peru, Bolivia, Colombia, etc), I can't identify on your bowl any hint to make me think it's south-american.
4. The hallmark pictured is not very clear, I can't see very easy if it's an eagle, a double headed eagle, or a crown, or a papal sign, or a ghost, or an angel, so I can't tell you more. Can be the city mark for Frankfurt, or Lübeck, or another one from the numerous german states, but they never used 900 silver and the hallmarking system on that era was in loth, not parts per thousand.
My 50 cents guess: (but I can't be sure, so take it with a pinch of salt):
Your plate was part of a collection, made in Moravia-Bohemia by a private silversmith who worked only for one client (a local baron, grõf, count, whatever, anyway, the eagle in shield could be his family's heraldic sign ), so being in a personal collection of silverware made on order, they didn't sent to assay office their work, to avoid the taxation. The style and the 900 mark is late 19th century, or early 20th century before WWI.
I hope this helps.
Cheers!😘
