peavey 112E or 115E Ext. Cabs

[mojojive7]

looking for a pair of peavey 112-E extension speaker cabinets, loaded or unloaded cabs. They were built originially for steel gtr. but were discontinued. Factory built w/12" Black Widow. I am also interested in the 115-E cabs. Same deal, but with 15" Black Widow. These cabinets are quite small, cube-shaped, and I believe they could be converted from closed to opened by removing the rear panel. Thanks
