Don't think the 'new' Lanc had the 'G' George markings, but last time I built it was soon after its release, in the early 1980s. The 'G' George kit, far as I know, was the original 1950s mould, re-released as part of a marketing tool in the 'up and down' years of Airfix ownership. Strangely, in the book I've just bought, covering the history of Airfix, this particular kit is not mentioned, although the history, and 'ownership', of the moulding tools is given quite a bit of coverage.
When 'G' was re-released, the original artwork, showing it landing with an engine burning, was 'modernised' and further detail added - the same basic scene, but much more 'alive' than the very basic original artwork.
