SLIK Tripod 112AF Pistol Grip AF2100 Ball Head SLICK

I have no knowledge of tripods or ball heads.
A quick search revealed that the AF2100 has been discontinued.
It is a grip-type ball head independently developed by SLIK in 1987,
and has received the Good Design Award and the Long Life Design Award.

It appears to have been purchased in 1993.
It has been stored at home for many years and has scratches and dirt.
The paper box is aged (photos 16-18) and the top packing is missing, but I will use it as packing material.

Please check the photos for size and condition.
