New to the forum, but have been skulking around reading it for years.
Your 68 is beautiful...fond memory for me...My parents remodeled the house in 1962 and also decided it was time for a new vacuum. My mother took me with her and she let me pick it out..had a choice of the 66, 67, 68 and the rare gold one at the time (I forget the model #). I chose the 68 because I loved the color, though she tried to talk me into the 66, as it would have matched the new forest green carpet better! Also talked her into the attachments, but she didn't buy the deluxe set, since we already had a Constellation 82.
