Mysteries found in a WW2 commando grouping

[Mike B]

Any help would be appreciated in helping identify a couple of items found in the ephemera and insignia grouping of a Royal Engineers / Combined Operations Pilotage Party (COPP) veteran. For a period the veteran lived in the Southampton area. Several non-military items were included and the veteran was an active member of The International Brotherhood of Magicians. It would be great to identify the attached in understanding the veteran more fully. So far my research of these items has been inconclusive, and any pointers on where to research further would be most welcome - Thank you - Mike
