Product Numbering & Bar Code Verification of Phantom Plarail Sets

If it is a company policy to keep their past material and archives confidential from the people outside their organisation, totally understood.

What would be the point of a company policy to keep their past material and archives confidential from the people outside their organisation? It's a toy company, not the Ministry of Defence. Would there be any damages for a company like this if the information of their past products is widely known? If somebody wants to know something about the past products he has to follow the rumours and investigate or wait for years for some product to appear on an auction to verify its mere existence? Even before the computer era, there were ways to keep the information on the products. If they somehow lost the information on some product, they could say so.

Sorry, to me this is not at all understandable, this level of "secrecy" has not much sense, and if they don't respond on an inquiry about their own products addressed to them, that would be very strange company policy, if not also rude.
