The range is still owned by HLBSC, and is currently OOP.
It was pulled primarily due to the moulds deteriorating (especially in the eraly packs) to a level where Richard wasn't comfortable selling them at the price required to make a profit. Unfortuneately, during the original mould making process, the masters got pretty badly beaten up, destroyed in some cases, and so to make any new moulds would require quite a lot of work either repairing the masters and/or re-mastering some of the original 'master castings' - all of which is time consuming and thus costly, for what is an older range. I know Richard was talking about possibly looking into re-releasing parts of it t some stage (the later, less damaged moulds and possibly re-mastering some of that parts which might supplement his planned 'Ultra-Modern' releases)...
