Hi John and many thanks for your interest.
After a swift response from Rails’ investigation team and forwarding of photos of the model for inspection, I received a standard Returns link. It appears that I’m to return the model and will be reimbursed.
Whilst I’m grateful, I was rather hoping they could repair the model and return it to me as I adore it; I was even prepared to pay for any cost incurred.
Whilst I’m no expert, my own diagnosis is that the housings for the bearings on the axle aren’t deep enough to retain the wheels in position.
Unfortunately, they’ve no others in stock so I can’t request an exchange.
Heigh, Ho.
Jon
