People walking in park and one shot of political ( Loyal Ulster ) rally.
Loyal Ulster Demonstration / Rally. 1919 ?
Northern Ireland? Probably more likely to be London (see mention of Dulwich in last shot.)
(Not certain that the 3 shots here are part of same story.)
First a shot of several people including the Prince of Wales (seen extremely briefly, if it is him) approaching on walk in park.
James Craig appears in bowler hat and Edward Carson in Homburg hat either side of an unidentified woman.
Then LS many people - boys? - walk in single file across a field.
Finally; the most useful shot: political rally; with an orator on a platform; making a speech; banner held up on right says 'Dulwich Supports Loyal Ulster'.
Amendment November 2011: This is probably a rally of the Ulster Volunteer Force in Ulster
