I have a 16th century Japanese matchlock rifle.

I bought it to commemorate the one my grandmother gave to my Dad after WW2.
A serviceman brought it back to our small hometown and she bought it for my Dad.

Dad was a trader and at some point he swapped that one for some other gun.

I always admired it as a child, so bought mine when I had the chance. It is not in near the condition Dad's was, but brings back good memories.
