I have no idea. Bought this back in 2008. Never got the courage to tackle this project until 2011. But as soon as I started pulling it apart, I realized I was getting into something a lot bigger than initially planned.
Man hours would be difficult to compute. My best answer to that would be, "who cares? I am finally done!" Ha ha ha....
Total cost: roughly $2,000 (minus man hours).
Two different appraisals were given for its current worth. The first one was from an antique appliance dealer for $7,500. The second was from a local collector for $10,000. I asked him why his was so much higher and he said that they probably didn't account for a simple little original seal tag (that I never noticed) that shows the compressor lines have never been removed.
I doubt it is worth that much more just because of an original seal. I would guess that the first appraisal would be more realistic.
