Here I am!!! Gramdma does not own the National Treasure but she has a really well cared for Singer 66 with 35,000 of them allotted on April 26 1951. Now what makes this a special machine in my book is the position it came off of the line. It was only 377 machines from the last one in that was allotted for that run!!
As far as the value I think you hit the nail on the head $250 would be reasonable for the excellent cosmetic condition it is in and the fact that I like the Blond cabinet. BFW and I both agree on the wood stain and I wish that most of the cabinets were the blond finish.
Tell her that she has a VERY nice machine and she should be very proud of the condition that she maintained it in.
