Maureen:
I'm very sorry to hear of your husbands sudden passing and wish you and yours all the best moving forward.
Reading your message I have a few comments.
The Kendall company manufactured hulls 1 to 31 as a flush deck 32 ft boats. Hulls 32 and onward were usually with a trunk cabin. The 39 foot may refur to the length overall.
See https://www.westsail.org/westsailcorporation for more details.
Valuation of vessels should be compared against other similar vessels on the market. Here are a few sites listing Westsails.

From your description of the vessel, I would have to say that you are selling a hull with a few reusable items and probably a soft deck.
Someone who would purchase the vessel would need to plan on spending years and 5-6 figures to remodel/rehab the vessel to a sea worthy - world cruising condition.
If you wish to contact me at - webmaster@westsail.org I can comment futhers.
