Kim,
You have the knack of pissing people off down to a fine art.
The previous poster suggested that Meccano might have been short of cash. They might well have been short of money, or they might not. And I doubt if you know enough to state categorically one way or the otherl. What I have read of what went on suggested that there was more to Hornby's decision than lack of cash.
Hornby had several other successful product lines which would have generated cash - Meccano, Dinky Toys and the clockwork 0 gauge line. It might be interesting to know what the sales returns were for the individual lines. I suspect that the Dinky line was the biggest seller since I remember everyone in the late40s/early 50s having Dinkies, but no where near as many having Meccano, etc. Dinkies were toys which you tended to get at any time in the year because of their lower unit cost - Meccano sets and model railway sets were Christmas or birthday presents. So a persuasive BRMSB might have been able to persuade Hornby to look again at their 00 scale line with a view to adopting different standards.
Jim.
