The kit was bought in December 2002 but I started building (I think) in 2005.
I don't think the casting of the conning towers differs much because quite a few things you see on the picture were changed or added by me over the years.
For instance the rear guns are not the originals, the vent grill was not included in the kit but added later on. Also the walking cane (I presume you know the story behind it) was made by myself. The "bulb", down left of the square antenna, was added with the idea of a housing for navigation lights (still not completed).
One thing is for sure, my kit did not contain any photo's , just a drawing and a "meagre" instruction.
