Unfortunately, Sam does have a habit of contradicting himself and stating the obvious.
A few weeks back, during the Deltic review, he was claiming Accurascale was much better than Bachmann with regards to fit and finish, now in the Bachmann 37 review it is much to the contrary.
I have one Manor, two 37s and a 31 on pre-order with Derails and Accurascale and that won't be changing in favour of the Bachmann 37 variant.
