Colin,
No, it isn’t that. The disk on the sailing ship SVAERDSTAD sold very well on Specialist Auctions and is still going strong. I direce viewers there from my website. I produced the steam/motor ship disk in response to many many requests world-wide. On the first day on Specialist Auctions, 7 of them went – since then zilch! Ebay brought not a single sale and they have sold dozens & dozens in the past. I think it is more of lack of interest in steam or motor. Wish I had never bothered now and stuck to sail. But I can’ imagine I will write any more. The steam/motor one took a year!
Anyway, I have decided to wind down now, although I will still build, but more slowly.
Bob
