I'm looking for information on khopeshes. There was a nice old thread here, but unfortunately it's images are dead.
Is there any work on them available? I'm looking information on different measurements, lenghts, weights etc. And I wonder if anyones made anything resembling a typology of them?

You could try searching/asking on Bronze Age Center. It also has a more active Facebook page of the same name.

Also, Google for "Neil Burridge" and "Bronze Age Swords". But be warned: you'll catch some serious bronze fever if you do. ;)
