Welcome to the forum - and yes this is the place to be! Yep - the baby, mamma and papa bear stoves had single doors so easy to tell apart from the double door models. Good luck with the baffle install and be sure to post pics if possible before/after. So I'm confused does your stove already have the round baffle just below the exit flu or no ? I understand certain stoves had that as original to the stove and others did not. I can't recall if anyone with top exit is running both the round baffle just below the exit together with a smoke shelf 'baffle' horizontal from side to side. If it were me I'd probably try both!
