Short story: Found F/B Marketplace AD "Wood stove" $100. Window glass broken, when movers carried out of house to the garage. This stove, a top vent MK ll, the user actually burned coal in it, wood occasionally. Grates are straight, baffle is perfect, no wobble on the doors, or shaker. Half the bricks had cracks. I broke them taking them out to lighten the load. I'm going to prep and repaint the inside. I think stove polish will renew the outer shell. New glass, bricks, and gaskets, and we have a nice stove. Oh, and it's heavy...built like a tank!!!!

It's still in SUV...Pics later

Nice score!
I've sanded and repainted my Mark I twice so far, the most recent time I used black brake caliper paint from the auto parts store, it's got a higher heat rating then black engine paint and I did it a few months before it was time to fire the stove so it cured for a while. Was surprised the stove didn't smoke up the house when I first lit it.

Pics..don't know what happened there.
Gutted the stove, and discovered a design flaw, or, this stove was built on 'Monday morning, real early'!!!!!!
On the back wall, the tray that holds the bricks, has a 1/8" gap, from one side to the other. I put a straight edge on the wall...not warped. The front tray is sealed tight. That's a 'major air bypass route' around the grates, up behind the firebrick. I'm planning on sealing it with Rutland furnace cement, unless, somebody has a better solution.
Also, when wiping down the stove with cleaner, on the lower right side, around the corner from the ash door hinge, there is a metal stamp-MK ll 2892 LM/05 R/3. The stick on labels are 'long-gone'. Anybody know Harman's codes?

UPDATE: Replaced the load door gasket, window glass & gasket, the ash door gasket, and stood the front bricks on end, increasing the height from 4 1/2" to 5 1/4". That puts the top of the bricks below the bracket bolt, leaving the full window view. 'Kudos' to forum member 'Bear038' for his MK ll post. On the outside, I was able to bring the shine back using Williams polish. To finish, I need to drill/screw/ tape the vent pipe joints........and we 'are ready'!!!!! I'll post 'finis' pics when Lill downloads her phone to the PC.

Form............
When reading the MK ll threads, a poster stated Legacy was bringing the MK ll back into production,so, it's possible. I believe Harman stopped production of the MK ll in 2013.
When looking down into the vent, you are looking at the baffle, which extends from one side to the other. What you can't see, is a baffle(like a snow plow) between the stove top and the horizontal baffle slowing the exhaust from going straight up the chimney. This is my first Harman, so, we'll see how good that works. This unit is pre 2013, but was not abused. I'm anxious to see what it will do.

I have seen Brand new Legacys near me, 1,2, and 3.
They all were rear exit draft, so that is what generated the question.
I love the Harman/ legacy spiral smoke exit design with a tiny draft built into the front door.
Very well made and reliable coal stove that holds heat well for a long time.

UPDATE: 11 AM Monday, lit the new to me Harman MK II with 40 lbs of Blaschak nut. I always enjoyed the 'blue lady's' with the Chubby 'Fireview' door, but the MK II is like a big screen TV!!!!!.......amazing....what a show!!!!!
OAT: Day-low 50's/Night-mid 40's......5 to 10 mph wind and raining
Stove temp with magnetic indicator: 150*-upper left side above firebrick
Flue temp 18" from stove: less than 100*
Primary air: almost 1/2 turn open
Chimney: 25 ft. 8" x 12" tile flue with a cap
Manual damper: wide open.......might have to adjust with the wind increasing today/tonight(a New England Nor'Easter)
Basement temp: 68*
Harman MK II: Idling
I think we have a 'keeper'.........we'll know for sure when it get's cold....

Sure looks good. I like the idea of putting your rear bricks vertical. That way you can really put a lot of coal in and bring back the true meaning of the word banking. I have done this with my TLC 2000 and it makes a world of difference in tending. I usually build up my coal bank to the top of the rear bricks then taper down to the front. It is amazing how the coal burns to the back, heat sink. I usually throw all my coal to the rear and let the fresh stuff fall forward. Usually the back bank is all I do, when I feed mine. I have mine idled back since I started it last Thursday and only shook mine down 3 times since then. I still have yet to take out my ashes, which I probably will do today. This TLC is really efficient. I think you will love your Mark 2 once you get it dialed in.
Good luck with your Great deal.

Looks real good. I'm sure you will like it's performance and ease of operation once you get everything dialed in.
