My first encounter with a Filipino slam fire rifle. Acquired it with other Philippine stuff including a sword cane.
Village made, it' heavy and has a smooth bore barrel, wooden foregrip has some carvings, the butt stock is plain. Brass / copper (?), bands secures the rifle together. Check out the shell ejector, spring steel
It amuses me that it has a front post sight..
Could be a Moro piece, okir adornment on the bottom brass strap of the stock.
Comments on it's age and possible area of origin?
