The only cased double gun I have, with accessories, is a Perazzi MX8. Since there were no qualifications ........ my accessories are: Allen wrenches for the GraCoil, a long, homemade, 5 mm Allen wrench for the drawbolt, an extra trigger group, a Giuliani spring and firing pin kit, a screwdriver for specific buttstock screws, a syringe containing a thin grease, and a small Ziploc bag containing a rag saturated with Ballistol for after shooting wipe downs.
Not much to look at I'm afraid, but it is all in a nice Negrini case, thanks to John Boyd. When those items help to keep me up and running at a shoot it indeed "adds to the experience". No big secret, I'm a pragmatist when it comes to shotgunning.
My vintage doubles reside in leg o' muttons, with no place for accessories.
