White Brothers E series exhaust discs

[Tom]

If anyone has any exhaust discs for a white brothers E series i'm interested. Probably need another 4 or so, but will take any number.

As a quick fix,
Can you insert washers to imitate the space that a plate would assume Tom, .. for a test?
I have not had the end out of an E series and are unfamiliar with its design internally, but are just thinking... ;)
