This is a high precision mount capable of handling up to 130 lbs of instrumentation. It formerly served at House Mountain Observatory in Virginia where it carried a 16in Ritchey-Chretien reflector and a 130mm refractor simultaneously.
The pier is a 10 inch diameter 42 inch high aluminum tube attached to a 2ft x 2ft ½ inch thick steel base plate designed to be bolted to a permanent base or pier. It might be adapted to serve as a portable mount with some modifications. It is not a Go-to mount, but does have encoders and a Meade C.A.T. system.

R.A. drive: 12” 285 tooth worm gear
Tracking Precision: <15 arc second total periodic and random
R.A. Circle: 11.4 inch, 5 min divisions, clock driven
Dec Circle: 11.4 inch, 1 degree divisions
Davionx 115v Quartz Star Drive

Assorted counterweights including 1-50lb, 1-20lb and various smaller weights are included as well as mounting brackets and plates.
The mount is located in Lexington, VA. Due to the weight of the mount and accessories, I would prefer it be picked up by buyer rather than shipped.

Telescopes in photos are not included.
