Just acquired a S-C 1903A3, and really struggling with the very fine front sight blade, when shooting in my club’s inside range. Just can’t pick it out, my eyes aren’t what they were!

I don’t have the same issue with my Lee Enfields or Swedishicon Mauser, which have wider blades. I have found mention of a wider 1903A3 blade, but cannot find a UKicon seller, or a US one that will ship to the UK. Any information on possible sources much welcomed!
