I think this fridge might be older than 1966. By that time, based on a multitude of GE BF fridge threads here, these models had devolved to basic, non-spill proof, metal rung pull-out shelving.
I'm pretty sure the reason for the sale of this fridge was revealed at the end of the video clip. It blocks the kitchen door from opening. The smaller, not-as-wide version of this model would fit perfectly.
It's a beautiful fridge, but considering the failure rate of GEs from this period after 50 - 60 years in operation, $650 is a considerable amount for what is likely to be a temporary situation.
