Alex/Cav, slight oddity with the packaging. For some reason the plastic which "seats" the right bogey is a different depth to the left side. It's slightly shallower and forces the bogey upwards, to sit at a bit of an awkward angle. It's minor but should be easy to fix.
Lovely model though!!!!!!
Given how similar they are to the BBA, could you please produce these 13x BWA which Baz mentioned a few years ago:
