A picture of the figured mirror in Brashear's workshop. The calendar shows the month as November, 1915. We don't know if this is the month the image was taken.
A picture of a early wooden model of the telescope and part of the dome structure. This is likely sitting in the offices of the Warner & Swasey Co. who built the telescope.
A picture of the lower half of the 1/10th scale model of the telescope and dome that was built by Warner & Swasey. This is an excellent image of their workshop showing a series of lathes powered by leather belts all connecting back to the power…
A picture of the almost completed model of the telescope and dome. The telescope and dome could be moved. The telescope was moved by inserting a rod into the base of the telescope where it connected to the gears. This model was exhibited in the 1915…

A picture of of the completed model in front of the assembled telescope in the Warner & Swasey factory. It was standard practice to test assemble large structures before they were shipped to be erected at the actual site
A picture of the test assmbly of the dome structure at the Warner & Swasey factory in Cleveland, OH. Large structures were test assembled at the factory before being shipped
A detailed picture of the dome assembly at the Warner & Swaseyfactory in Cleveland, OH. This shows the shutter opening and the drive wheel for opening and closing the shutter.

A picture of the original clock drive for the telescope. At the time the telescope built, the best way to move the telescope to accurately track the stars, was to drive the telescope by a mechanism that was powered by a falling weight. Very smooth!…
A picture of the polar axis of the telescope out side of the Warner & Swasey factory. The polar axis is accurately aligned to the axis of Earth's rotation so that the telescope can properl;y track stars.
A picture of the handling cart for the mirror of the telescope. The mirror was coated wit silver than had to be replaced every few months when it tarnished. The mirror was lowered into this cart so it could be easily moved.
A picture of assembled telescope tube outside the Warner & Swasey factory. John Stanley Plaskett is in the right, in the middle is Ambrose Swasey. The man on the left is Edward Burrell and engineer of Warner & Swasey
A great picture looking down the tube of the telescope at the mirror cover. The cover was very important for protecting the mirror from the elements and from anything being accidently dropped onto it.
A picture of the construction of what would become the Director's house on Observatory Hill. The north pier of the telescope is visible in the background
A group image of the dome assembly crew. Note that the two engineers, one holding the blueprints, are clean compared to the workers. This picture was taken inside the dome.
A picture of the steel structure of the dome mostly completed. The cement pier is visible inside the dome, and a crane and the water tower are also visible.
A picture of the dome with the steel structure completed and the lower half of the outer paneling completed. There appears to be snow on the ground around the bottom of the dome.
