Unknown Mfr/Model

[lancerosmaier]

I' replacing the surplus tent stove in my shop with a stove of unknown origin
It's in fair shape and, as it's going in the shop it only needs to be serviceable
The stove body is 20 1/2 " wide by 14 1/2 inches deep
Has a heat shield on the back and a fan located in the base
Door has a tree engraved on it (see pics)
There are 7 holes in a lip just inside the door that appear to be air inlets(?) and there were 5 bolts in them when I got the stove

Can anyone help me I.D. this? Mostly interested in the "air inlets" - what they really do and perhaps why 5 blocked.
Thanx for your help!

Not much to work on here, any make/model/testing plates on it?

Yeah, there are no identifying labels, tags or other on this thing
Was hoping that tree on the door might've been manufacturer specific
Or, those "air inlet" holes inside the door might be unusual - have installed several stoves and don't recall them
