Don't they make them in Bradford?
Yes, Bradford, PA. I think they often do runs though, and when a run sells out, they aren’t necessarily making more.
My guess would be the prohibitive costs of international returns.
With regard to dealers not shipping internationally at all, I suspect some have simply concluded as a business decision that the profit to hassle ratio of shipping internationally isn’t high enough to be worthwhile.
With regard to manufacturers prohibiting it, I suspect it is to protect their local dealers from having to compete on price with US-based websites.

I’ve ordered from there before; no issues.
I checked a couple of other sites that ship internationally. Both did have lists of manufacturers that prohibited international shipment of their products. Neither had Case listed, so perhaps a recent change that hasn’t been added yet?
