Hannover I Front Door Latch Broken

I started using a Hannover 1 coal stove this winter. Totally new user here.
The front door has always been stuck. It turns out that the latch is completely rusted and stuck.

I'm looking for recommendations for where to find a replacement latch and for how to replace it? I'm in upstate NY.

I'm handy with this kind of stuff, but if others with more experience recommend to have an expert do it, that's fine.

Also, what's the danger of running the stove with the front door not completely sealed?
I made a little contraption with copper wire to keep the door closed, but it's not fully sealed as when closed with the latch.
thanks for the help.

Thanks for the reference.
I looks like they sell it through a distributor (http://www.bierlygroup.com/saey/parts3.htm). Based on this info, the part I need is 878-0036-430.

Now I have to figure out how to remove the old knob since it's so old and rusted, it's pretty much fused with the door. If anyone has suggestions on the best process for getting rid of this, please post.
thanks

If this is the latch your looking for, it's just a nut that holds it.
You'll probably have to soak and beat the old handle out.

Yes, that's exactly the one. Except the one I'm looking at in my stove is 20yrs old and super rusted.

I've tried some WD40 and a few bangs, but it's super tight there. When you refer to soak it, what would I soak it in?

Hi burningMan1, I like the home brew of 1 to 1 tranny fluid and acetone if no PB Blaster.

Use a good penetrating oil then work it back and forth with a wrench until it
comes loose. Then tap it out.

There are better things than WD40. Vibration is the only way. Let soak for a few days and then grab hold with a wrench or long pliers and while putting stress in one direction hit the wrench with another to set up vibration. Do this in both directions. Once you get the slightest movement it will free up. Some heat around the shaft will help but do not overdo.

Last resort, cut nut off with zip wheel.
