As others already indicated, the pommel does look suspicious, a far more traditional form would be as in the picture below, but without actually examining the item I would not declare it a replacement.   
 
The grip wire is undoubtedly rather poor replacement.  Most good examples of that style have finer grips.  Here is the picture of the similar rapier, where I redid the grip wire - it improved the appearance quite a bit.
