Early 37mm With Lead Driving Band

[doppz92]

Hello, I've got this projectile and it looks pretty much like an early 37mm made around 1880, there's no fuze, it's a plug. I would like to know which kind of case I need to complete the round, has it got to be a coiled one? Thanks

Hello,
I know it as an inert round made for trial by Puteaux (1880's)
