My father died in 1993 and his widow in 2021. I am cleaning out his gun case which has several cleaning kits and accessories. This is one of the kits that is offered, that seems the most complete.

Vintage Hoppe's 9 Gun Cleaning Kit in Orange Case (Used)

NPS #9 - Approximately 1/4 Bottle

Patch Cloth - Approximately 3/4 Box

Lubricating Oil is over half full

Rod End Accessories:

Nylon and brass jags

2 bore brushes

also included is a cotton bore cleaner. I do not think it was originally part of the kit. I think it is for a twelve-gauge shotgun.
