Shedstove

Thanks for the replies..However I am still no closer to finding the make of the stove!

Hi! I'm creating a Covid refuge in my shed, and would greatly appreciate advice on my wood burner. (See photo) I've installed thai big heavy wood stove but to my surprise this stove has no maker's name or plate attached. So I can't find out how to check if I need spares - esp. if it needs baffles or fire bricks (neither of which it has at the moment). With a straight up flue it's working OK would baffles and firebricks make it better? I would dearly like to know the make. Thanks.
