I would say someone built up a Sambar rifle by the looks.

Custom stock with a shortened barrel as well as a barrel band sling swivel added.

Not original but that is a good thing as it is the same mods I would do.

The Brno's came into the country with the set trigger fitted and the standard trigger in a cloth bag with a bolt take down tool.
A lot of the standard triggers were lost.

Daryl,if you have any standard triggers you dont need I will buy them from you.
