Hi DoubleD,

I asked about the markings on indiansforguns website. One of the gentlemen there translated it and I believe he is right.

It is written :

Shri(a salutation) 3 Chandra Shamsher Jung
Year 1967 (Is as per Vikram Sambat = Hindu calender. It is a popularly used calendar in India and the official calendar of Nepal)

No. 130

Shri 3 Chandra Shamsher Jung Bahadur Rana was the fifth Prime Minister of Nepal from the Rana dynasty.He was born on 8 July 1863, and died on 26 November 1929.

The year marking 1967 (As per Vikram Sambat = Hindu calender ) means 1910 (As per Christian calender).

Now that you have what you wanted, could you please tell us about the gun? Thank you.

Best-
Vikram
