RRS mini bell question

[flat train]

I've seen many min bells with text on the rainsheild saying "WRRS CO" but I've also seen some railsheilds saying nothing, Could rainsheilds with nothing on them be RRS?

Sometimes, but the door on the back would also have to be blank, IIRC.

Also, as the owner of a WRRS mini-bell with a blank rainshield, they have RRS cast onto the inside of the rainshield, where it ain't really visible.
