Bluing tank components for sale. Tanks, pipe burners and tank stands bought from a retiring gunsmith's shop years ago. Tanks are 8" x 8" x 40", 1/8" thick steel (black iron?), larger and twice as heavy duty as Brownell's tanks.  They still need some cleaning up and I have not used them other than once boiling water for rust blue. Use for parkerizing, rust blue, hot blue, etc.  

Tanks $150 each.

Pipe burner - $75 without mixer (has 1" pipe thread), $150 with mixer, $200 with mixer and orifice and hose set up for propane.  

Tank stands $200 each.

If the posting is up it's still available no need to ask.
