If you had a photo of the shaper on whatever stand it is on, that would cut down the possibilities as to what the possible heights are. But to answer the question of all possible heights, one must consult several catalogs. Atlas sold the cast iron legs either with or without the original factory wood top and shelf for the 10/12" lathes (in two different lengths), for the shaper, and for the mill. They also sold two different length hardwood cabinets for the lathes, plus one each for the mill and the shaper. And at a different time, they sold all of the same options in a steel cabinet. And unfortunately in this case, unless you have proof that it is sitting on the correct one sold for the Shaper, the Shaper will physically fit on most if not all of them. So the only safe option is a measuring tape,
