Well box of dreams arrived this morning.
First impressions? Very impressed the level of detail is not something we've seen on a "modern image" carriage before and is welcome - also for the price they represent great value for money. Finish is excellent, particularly nice is the different satin/gloss finish to the two sides of the corridor connections which represents these well.
Word of warning: I don't know if these have been "forgotten" but for some reason the footsteps on both my models were only held in place with luck... and promptly fell off! Fortunately all were recovered and simple enough to refit with a dash of superglue - you have been warned!!
I have managed to take my TSO apart - something I don't recommend! Body simply clips on, but you need to detach the ETH gear first - the "socket" on the chassis does actually come apart for this purpose, though I don't discover that until afterwards! Also I would recommend removing the couplings from the sockets first, as the chassis bends the close coupling mechanism self destructs and then jams between the chassis and the interior! To solve this I had to remove the interior (3 screws) and then carefully reassemble the mechanism.
I can confirm that when apart there does not appear to be any provision for lights, not that fitting lights would be particularly difficult.
Colour - I think we were balloted on this if I remember right? It is always a subjective question, only the buff colour really comes into question, and it doesn't match other companies attempts, however looking at photographs and video I would say it is probably closer than other attempts - it is very subtle and doesn't show well in the photos on Hatton's website.
On the whole though and excellent model and for the price well worth investing in - as others have said I hope Oxford expand their range sooner rather than later! HST trailers would be particularly useful!
