SU35,
Good deal!
As Klik says, No. 1's are great with irons. The buttstocks are actually dimensioned more for irons than scopes, and the rifles are much handier without scopes.
One option you might want to eventually try is the NECG aperture sight. I used one on a No. 1 .375 H&H for a while and took a number of animals, including a Cape buffalo at maybe 60-75 yards, and a lechwe (about the size of a northern whitetail buck) at over 200. In theory the rifle should have kicked harder without the pound or so of a scope, especially with the load I used, 300's at around 2600. But it actually seemed to kick a little less, because it fit me better.
