ErikD,

The one I shot in 416 (and a 375H&H I saw) both came in Blue, Velvet lined cases
\and were the 100 year anniversary models by ? Mauser.

I think they had somethig like this on the barrel.

As to who made them, I don't know but I didn't like it
and I wouldn't pay $10,000 for one and there's plenty of Bolt action
rifles I'd pay that amount or more for.

Anyway, Hope this helps.
