Payback isn't straight away, though, it's over several years, even decades, and I suspect they'd be aware that Hornby's initial prices were artificially low as has been said as introductory prices so were more than likely to increase, as they have. To me Heljan backed out with undue haste, if they were serious they could have had their 31 out long before Hornby's. Anyhow, as usual, just speculation! Keeps the thread going until the arrival of the HSTs and 50s, though I'm not interested in them or a 66, it's what comes next that interests me!
