This is a Corgi re-issue but not from the Corgi Model Club, although it is no doubt based on their re-issue of the 335 model by the Club, for which Corgi will have supported with funding.
First available in April 2023 this is one of a small number of what were referred to as 'heritage' models in Corgi's online store. Not widely promoted, however, and just one batch was produced in metallic blue and they have not been available from the Corgi store for a long time.
There has been since a batch produced for the Corgi Model Club which looks like an identical model but not one that was available for subscribers, available from the Club's store only. I believe those currently available are from a second more recent batch and will have different box labels.
The box is a nice reproduction in similar style to the Club issues with various text differences and the data panel on one side. This will distinguish the model from any existing or subsequent 335 issue that may be forthcoming.
Although a recent issue, this is likely to be a sought-after model in future due to its limited production and availability.
