You might want to use a little caution in equating  "beehive oven" to being
a baking oven for bread.    In SW Pennsylvania there are a number of
standing beehive ovens, but here the term is used to reference coke
ovens--an early style of oven used for making coke for the steel-making
process.  Baking ovens in this region were more typically rectangular in
shape than of a beehive shape.
