Mike, according to the Maxwell plan I've got here the overall length was 125' by a width of 24'8". These dimensions do not include a small extension, which on Maxwell's plan measured 14' long by 10'4" wide. It was located on the west side of the car shop, 35' in from the southwest corner of the building. Also, the main structure measured 16' from the ground to the top of the sides. I've got some other stuff (info and conjecture) here which pertains to the structures once appearing on the west side of the building, as I once researched and built a model of it in 1/4". I'd rather not have the rest of this out in cyber-land, as it is, as I said, a mixture of conjecture and somewhat educated guess on my part. If you'd like to hear more about it, please contact me off the board. Greg.
