I bought the Frosted Extreme Detail version Feb. 2016. The "extreme" plastic version has a much less rough texture to it than the "ultra" finish plastic I've gotten on other prints and so is definitely the way to go here. That said, the fine detail on this model is too fine, and breaks off just by looking at it. Mine arrived with a handrail already broken off and missing, and two other handrails broke shortly afterwards simply by me picking the print up to test fit bogies. Brake wheels, lamp irons and even buffers are just too fragile for normal use. I will be removing and replacing all the handrails with wire and replacing the buffers and brake wheels, too with stronger parts. The lamp irons I will just leave broken, as is as they're too fiddly to replace.
The basic body is OK. The top and ends will need to be sanded a little to remove faint print lines and there are some noticeably uneven seams along the sides that I will have to file down to make flush, but standard Farish coach bogies fit just fine, look right and swivel and run on the track well. In short, this print might be better just as a basic body with the details (handrails, etc.) left off to be fitted by the purchaser with separate parts.
