This one came on the market in March 2013 and was bid up to a final price of $1,900. Very nice example, original pickup, and comes with its OHSC.
"Up for bid is a beautiful Dan Armstrong bass guitar. The condition is as if it was in a time capsule for the last 43 to 44 years. All chrome is rust free and looks like fine jewelry. Tuners are original and as new condition. The body is in beautiful condition with no scratches or missing parts. The finish on the neck is all original and in great condition. I do not believe there is another Dan Armstrong bass in better condition than this one. The bass will be supplied with the OEM case. The case is in good condition, especially for the age. Please see pictures. If you would like additional pictures please let me know. Serial # D904."
