Some of the stats of the Wallace collection sword may be found here along with a discussion of this type of sword:

And here are some stats from the Higgins Armoury's example.

POB and distal taper are not usually something museums bother with. However, you may be able to find the information that you're after by searching HEMA, WMA, and ARMA sites. ARMA would probably be your best bet.
Hope this is of some help.
