This is actually one I picked up in Nepal back in 2005. It is also Shree Chandra marked & also carrys another indistinct marking.{shown both ways up for clearer image.}
श्री जंग ५(?)/४६
श्री ३ चन्द्र
śrī jang 5(?)/46
śrī 3 candra
Shree Srijung Battalion
It has a 14 3/4 inch blade, 11mm thick at spine & weights in at 32 1/2 ounces.
The Shree Jung unit apparently specialised in Prime minister & Durbar Palace security in Kathmandu.
Heres an image of there regimental standard.
