I think its got to be a Krick as I was working my way through a pile of magazines which were also being thrown, and have found a torn part of a plan which identifies a sub and the manufacturer as Krick.
Having said that Ive looked at current pictures of the Krick submarines and would hazard a guess that someone has been using poetic license with this model as the dive fins bear no resemblance and there are a few other cosmetic issues.
Still got about another 100 magazines to work through so perhaps some more of the plan might turn up !!
Does anyone have contact information for Krick as it would be useful to see if they have spares etc.
