Here are three
versions of the "Sold Out of Service" opposing broad arrows. The
broad arrow, as you may know, is the symbol of the British War
Department. The overall meaning of this marking is that the weapon
was released from Military service, or "Sold Out of Service". Often
they were then sold to the public, or to rifle clubs. This marking is
generally seen on the right and/or left side of the action body,
knoxform and often on stamped into the wood of the weapon's
buttstock.
Opposing

Opposing

Opposing

or "Serviceable", and did not need to be reproofed if sold
in England.

Arsenal. Firozpur is located in the south-west
portion of Punjab.
