This is the Pommel cap of a Late Saxon sword.
The original was made of Copper Alloy (Somewhere between Bronze and Brass most likely) and was found in Hindringham, Norfolk, UK.
The Replica is near enough 1:1 with the original and is Hollow, just like the original. The Typology appears to most closely match that of the Type L, but it is not exact.
I've been told there is a slight undercut to the ends of the pommel - to fix this for casting in Metal, build up the hollow with plasticine, wax or some other modelling compound. Sorry about that.
The Hole for the Peen is much too small, and intentionally done this way so you can enlarge the hole to suit your sword's dimensions.
This Pommel is paired with the upper guard linked here:

There is no crossguard model as the Originals tend to have Iron crossguards, according to the few surviving examples of this type.
