3ft by 4ft x 6inch surface plate. Collins MicroFlat, made in USA. Has ledges on the 3 ft sides. With stand (three point support) and plywood cover hinged in the middle. Downside is, it is in my basement, Edmonton area. Years ago, I got it down by sliding it down the concrete fire exit outside stairs on edge on a wooden sled and a come-along hitched to a truck. Might get it up the same way, or a truck with a crane. Because of the limited market for such a thing, and the challenging retrieval, the price is very flexible.....make an offer.
