Positive id and manufacturer, please.

Am attempting, over the Christmas period, to bring some sort of order to the untidy heap that passes as my collection of ordnance items, and this was retrieved from the depths of a dusty cupboard.
It appears to be a perfectly ordinary case shot, dimensions (approximately) 400mm overall, calibre 57mm, and sadly lacking its shot or other shell contents, and the headstamp is an enigmatic EP, with a (?) date of 98 and a star beneath that. Why do I get the impression that it is French or Belgian manufacture?
Can anyone help, pse.

Seems close to this one :

Pretty sure that that's the one. Mine is missing about 55mm from the bottom of the "skirt", but this ties in with other damage probably caused by the removal of the contents at some time in the past.
Merci, mon ami.
