2 kukri displayed at the Gurkha museam as battlefield or theartre pickups. The top one in Egypt probably from the 3rd Gurkha rifles the lower one from Gallipoli in 1915.
Neither look very official issue or standarised to me....
& then again 4 Gurkhas in WW1 displaying there kukri. Again not very standardised. Looks like at least 3 different types of kukri to me.
