Italian Vase, To be Identified.

I have started up a new category of posts to this site for “Unidentified” pieces in the hope that eventually someone recognises the maker.
Often the country of origin can by identified, sometimes by style, sometimes by technique or decoration…… but sometimes that is where the trail ends.
Here is the first, a piece which appears to be Italian – but could also be West German. A slip cast, and hand painted vase, 17cm tall. There is a stamped number in the base of the clay, but it is not clear enough to read. The style of numbering though looks Italian.
