Where have you seen a Ross for sale? Many fakes from India out there, a few who didn't pay attention have been caught.
Now for what everyone does not want to hear.
Unless you have a proper case for your scope, don't bother taking it on the hill.
I have seen pictures of
@Freeforester 's work and he makes them well, so does Norman Kelman of Achnasheen.
Cases will not be cheap, as you are looking at a decent cut of saddle leather, which takes a lot of effort to stich properly.
Material costs alone will be well over £100 if you consider the strap and buckles too.
Add labour and you are looking at over £350, and remember the boys need to make a profit (as they should!).
