This is a difficult one! I have seen the collection and the gentleman who housed them all was a keen model boater. The venue was very popular and there was an early year regatta each year. Then it stopped, I believe after he died.
The subsequent owners were not interested in continuing the regattas. My understanding is/was that many of the models were there as exhibits only. I heard one or two modellers saying that they never had the opportunity to reclaim their models.
Where does the truth lie, I don'nt know but they were clearly not appreciated anymore.
I did wonder what happened but I found it hard to watch the video when 'the dealers' arrived.
My only contact and experience was after one had gone. I had lost contact with a friend, he never said he was ill, a great pity. He was a prolific builder and all except the sailing boats were taken off for a pittance.
Later I sold the sailing boats for his widow and they went at fair prices.
