Map of Canvey dated 1943

would it be possible to post magnified section of this map, pin-pointing the position of the lighthouse, in relation to Canvey seafront? I was around 10 years old when it was decommissioned and in my memory, it was way out into the estuary. However, I have a vague memory of being able to paddle out to its base at very low tide, so perhaps closer than I thought.

If you click on the map you will see it enlarged
