This guitar came up for auction in December 2011 and sold for the $1,500 asking price. Looks to be in very nice condition and came with an RT pickup and OEM case.
"All original 1969 Dan Armstrong plexi guitar in GREAT shape with original case. No scratches or dings, original pick guard is in unusually good condition. Comes with original rock treble pick up. Date codes on pots date this guy as a 1969 model. Paypal only local pick up ok"
