I rather suspect that somebody at MHS has confused plans, which are owned by the company, with other goods that it acts as a distributor for and therefore may well be subject to contractual restrictions as to sale. We shall see. I shall post any further information when I receive it which won't be before tomorrow now.
Incidentally Model Boats magazine are certainly not losing marketing share, they are a long way ahead of their closest rival, which had better remain nameless and, in a very healthy position at the moment.
