I've just started on some Stuart kits I have (my post on the James Coombes) and noticed a marked difference in the quality of the castings. The Victoria castings were very nice. On the left the casting is from the Victoria c 2008. The photo shows how much smoother the finish is than the one on the right, from the James Coombes kit about 2010. (Been in a box under the bench…)

Here is a photo of the cross-head guides – these are quite rough too –

I've just bought a boxbed and base for a D10 and again the finish is pretty rough.
Have I just got a bad batch or have Stuart turned down the quality ?
