Hi 12CC try this link for the Europa CEPT 2007 issues which celebrated the 100'th anniversary of the scout movement, it has all the participating European countries listed with images
http://europa-stamps.blogspot.com.c...ears_22.htmlThere is also the 'Scouts on stamps society international' web site which will probably be your best bet.
Try auction sites like Delcampe for scout society postal stationary and you may consider the Mafeking emergency siege issue designed by Lord Robert Baden-Powell, the founder of the scout movement.
