I contacted Maciej over a year ago and we agreed on an historical piece to replicate, but the timing was not then right for me. After some back-and-forth, mostly on my side, the stars have finally aligned and this is going ahead, with an estimated completion time in the early Spring of 2016.
The project is based on a sword that was apparently sold by Christie's in 1991. It's a classic Brazil nut design with fairly large proportions (blade 88.4cm. Overall Ilength 102.3cm). The blade would be classified as an Oakeshott X transitioning to Xa. Its hard to date such swords as they were popular from the end of the 10th century through the 12th century, perhaps even 13th in some regions of Europe. However this sword has a few features (rather strong profile taper like an XII, curved cross, and rather long grip) that might put it safer in the later period; 12th century. There are also some partial large inscriptions framed by crosses on one side of the blade that might help in the dating if one has expertise in that area (I don't).
Below you will find Maciej's design and comparison to the original sword. The measurements of this design are as follows:
Full: 1203 mm
Blade: 884 mm
Blade width: 53 mm
Grip: 94 mm
Cross: 200 mm
Pommel: 90x35x30 mm
Expected weight: 1280 g
This will also come with a scabbard.
One thing I am not sure about is the grip length. Maciej originally estimated 105 mm. I know that a shorter grip (as one finds in most such swords) works best with my hand size and a Brazil Nut pommel, allowing one to leverage the pommel against the blade's weight in both the hammer and handshake grip (I've always suspected that this was the intent of their design). However, looking at comparisons with the original, 94 mm seems visually out of balance. Maybe 100 mm would be a better compromise? I'm not sure.
Let me know if you have any comments and I (or Maciej) will post updates when the come.
