I have one that was bought new in 1978 and used every winter since. It looks very similar to 6mm250's stove. I have had to replace the door gasket a few times. I replaced the blower motor 8 years ago. Other than that all I have done is use it. It is 6 above zero right now and there is a good hot black locust fire going in it. Nice and warm here in the house.
