Allen,
I keep my fingers crossed for you and your quest. Perhaps, the current situation is too simple to understand
Just based upon the facts in this thread, I would assume, that you called Elderly on Friday, told them about the history of the bass and your desire to buy it, and they just added an -not available anymore- to the ad to reserve the instrument for you...
I've had this Friday-was fine-Saturday-deal-was-blown-shivering-the whole-weekend-everything-turned-out-fine-Monday-Morning thing only once in my life, but it was a very special deal for me also, so here's wishing you that everything will be fine tomorrow,
Christian
