400

Not sure. I have a friend who has the identical gun in
one of the .475's and we discussed this. A lot of Watson Bros
guns were high quality and as such one of the premiere engravers
did the engraving - the name escapes me at the moment but I will
find out.

I haven't seen / handled the gun yet - it's one of my DR's
that is still overseas !!!
