My favorite is the No.4, prettiest rifle in the world. But as mentioned before, you have to list some more facts, because one No.1 MkIII is not like another No.1 MkIII, same for the No.4. Make, year, condition, all these and more are what you should be looking for. Are you looking for a WWI or WWII vintage?, what country of origin do you prefer (Britain was not the only place that made and used the LE, Australia, India, Pakistan, Canada, and even the U.S. all made there own Lee Enfields.) What are you looking for, a basic shooter or something with a little more collectible value to it?
