I was thinking... was the removal of sawbacks regulated? By that I mean the technical specs of the actual handling. I've seen different 'ways' in which this was done, one more thorough than the other.
Every removal seems to start at the back of the spine about an inch from the crossguard, in many (sad!) cases shaving of crowned stamps and dates in that location. I've noticed these types and included pictures from my collection:
1) Shaving continues over the entire blade and includes (most of) the false edge along the tip
2) Shaving stops neatly where the fals edge begins, creating a perfect symmetry and only removing the sawback itself and NOT the tip
3) Sloppy shaving resulting in a still visible sawback (like on some Turkish ones)
Here's an example of the sloppy kind:
Bavarian bayonet. Not in great shape, but an interesting piece. The crowned 'O 11' marking on the spine has been largely removed along with the sawback. According to Carter's "German bayonets - Vol 1' this company only produced for Bavaria in 1911, marked 'O'. By the placing of the remaining "1" - I'd guess this was marked "11" There's severe damage on the tip of the blade and the false edge, looks like someone used a hammer on it... Could this saw be removed by the Turks, or did they shorten all of their pieces?
PS: I'm sorry to bother you with exclusive queries about (and only about) this type of bayonet, but I limit my collecting field to exactly this one ;-)
