Up Periscope Game by Denys Fisher from 1975 (Rare)
This is one of my own games and one of my favourites.
I can not be sure of the exact date in the 70's when I got this for Christmas but I believe it was 1975.
The Game was a new Novel idea at the time with it not only being 3D but you actually use miniature Periscopes to locate Enemy Ships.
You take two roles in the Game: One is as a admiral  trying to get your Convoy across the Ocean to your Home Port Safely
and the second role is as Captain of a Submarine  trying to destroy the Enemy Convoy using your Periscope and Torpedos.
The Game is 3 Dimensional with the Board being Verticle and you on one side and your adversary on the other.
The Periscope slides along the Bottom and when you look through it you get a realistic captains view of the Enemy Ships.
This is a enthralling Game that you never tire of.
The Games Contents are Complete and in Excellent Condition.
The Box is also in  good to very good condition with some  storage wear to the edges,sellotape residue and creasing to the underside of the Base
but this is only to be expected.
This is a Rare Game by Denys Fisher which is much sought after by collectors.
