Hello Ian,
IMO, all parts of the hilt are not genuine. It really helps to include pics from additional angles to allow visualisation of features in 3D.
Not much hopes for the blade, too, albeit it being closer to the original shape. Here's a thread with genuine old-style examples:

More nerdy details on dimensions:

Antique pira blades seem to come in widely varying lengths and more research is needed to include full variability; not much hope for non-laminated blades though.
Regards,
