I have a very old Mandoos purchased in Muscat in the mid-1950's by my mother, Helen Humphrey. It was an antique when she bought it, so I'm guessing it was built in the late 1800s. It is solid teak, is covered with ornate thin brass, and weighs a ton. It has never been restored and is in very good condition for its age. This chest has travelled, let me tell you! From Ras Tanura to California, California to Oregon, Oregon back to California, California to Australia. It has always been packed out of sight from the time the Humphreys have owned it.
Somewhere on an Aramco website, I have seen an article on how a Mandoos should be restored, but I believe it has since been removed. So now I find myself wanting to sell this rather rare and valuable chest, but wondering whether I should attempt to slather some teak oil on it -- not that I personally would want to, or have the skills to restore it.
An anyone help?
