Ho hum. I bought a GCR Pollitt 4-4-0 on Monday night, it was delivered today but the seller posted me a very nice Pollitt 4-2-2 instead. Polite email to the seller pointing out their error but saying I'd be happy to keep the single if it suits them...
And we've sorted it out with the minimum of fuss. A simple case of the boxes getting mixed up, and as it is payday tomorrow I've bought the Single as well as the 4-4-0.
