Yours is in a lot better condition than mine (attached).
Somewhere in the shrubbery I have a service manual for it.
It appears you have most of the 'vanity' items; I have been led to believe a tailight is most difficult to find.
The only tales I have heard about them is that one sailor used to ride his on submarine decks.
Mine has been in my front window as a plant stand for eighteen years since it was "consigned". Last year or so, the owner's widow showed up with a ballistic boyfriend who had been watching too much "pickers".
If he wants to pay eighteen years of storage, its all his!
