The Hachette Bismarck series is not a commercially available kit, it can only be bought via Hachette on a weekly or monthly basis ie one mag per week via the newsagent or 4 mags per month direct from Hachette.
The kit originates from Amati so it may go on sale to retail at some point in the future but even then it will be only sold as a complete kit and not with magazines or on a bit by bit basis.
If your not to happy with building the model the basis advised then why did you buy into it in the fist instance, surely you were aware of this from the outset??
