These are very rare....thought to have made only about 60 or so sets....originally designed for the dual showman speaker cab...they are not perfect but are in really nice shape..cab is held by to slot screws that fit into craddle shown in picture 7....they measure 27 inches high and 18 inches wide...I do believe it came with a bar with wingnuts that would go into the slots shown in picture 4 to control angle of cabinet....see photos...this is what you get!!! ....Be sure and see my other listings
