Cooey 84 / 16 Ga Front Bead Thread Size

[alberta.elk]

Hello everybody,
I am looking for a Brass Front Bead for my Cooey 84 / 16 Ga.
I have bought one Brass Cooey 84 bead for it from a gun shop, but does not work.
Anybody know what is the front bead thread size of Cooey 84 / 16 ga.
Or where I can buy a bead for it?

Thanks
Alberta. elk
