I have a bunch of lovely cases with various accessories for my own guns and when shooting from home, never use them.
BUT when I go to Scotland or somewhere that will involve a gun clean whilst there, I take the lovely old case, put in all the lovely old accessories and use them as intended.
For me there is little so nice as coming back after a day's shooting (with perhaps little to show for it!) and fortified with a glass of single malt, cleaning and oiling the gun with a chestnut leather gun case gleaming in the fire light on the table before me.
Okay, that is a bit romantic but I have done it and I can still remember the setting and a whiff of No.9 brings it all back!
