Try Google, I did and found some for sale online.Where the heck can one find em?
Nothing on the exchange.
The M1918 bayonet is a proper issue bayonet for the K11 (kept making K11s until 1933), as is the M1899, M1914 sawback, and M1889/92 beyonet. With the M1899 and M1889/92 you need to make sure it has the 14mm bore not 15mm bore as they used the same bayonets for their Gewehr 96/11s and 1911s.The K31 bayonet will fit the K11, but they are different.
I don't know when the Swiss went with both sides sharp, but K11 and earlier Swiss rifles should have a one side sharp, with a deep groove down each side, with a rib on top. It will also fit the K31.
Original K11 bayonets will cost a premium over the K31 types.
