1980's Jotul 3...top baffle??

Hi,
I've been looking at some older Jotul 3's lately and I have my eye on one. I went to take a look and the top of the stove was detached and there is not a top baffle plate underneath...do these stoves have top baffles? Can anyone point me to an exploded view of a 1980's Jotul 3?

This is definitely a straight up "3" model. I'm looking at buying it (used obviously) for hearth mount in my fireplace. I want to gain some heat when we're having a fire instead of spending $$ to have a fire.

It looks like there are mounts cast into each side (inside) for a top baffle, but I'm thinking if the original 3 did not have a top baffle they probably used the same shell for the other models with a baffle so the mounts are still there. Seeing the mounts made me suspicious that a part was missing, but I've heard from a few sources that this model may not have had a top baffle at all (but I can't find an exploded view, or a "definitive" answer!).
