This was the plastic 2nd. Ed. bike box! The bike was sculpted by Norman Swales and the Marine by Jes Goodwin as per the 1998 catalogue page.
The 3-bike squad was announced in the September 1996 White Dwarf; I’m still trying to nail down the date of the solo bike box and whether this is the later release with the updated Marine or the earlier one. Based on the front cover being art rather than a model picture and the part number I’m suspecting later, but we will see.
More pics to come once I actually unbox it.
