Question about sideplate numbering convention

[DonVoigt]

Thanks Guys, much appreciated.

Wayne,
we were looking at military which would be all dated 1911-18, except for the few 1920/21.

But please do look at any and all you wish and report.

Any information is better than none.

Thanks again.

Tom and Mark,
would be great to hear from you on side plate numbers you may have.
