I have an old New Braunsfeld Red River;
She's 1/4" CR steel and a great little smoker.I have modded her for reverse flow,but only helped her efficiency.In my honest opinion(if you are selling) is to ask at least $200.00 for her. Those in the know will appreciate it(depending on condition).If buying and the dude doesn't know what's up,well
. Then take hima rack of spares when you cook on it.
Hope that answers your question;good luck and
SMOKE HAPPY :)-
