Cec's medals: the rare Meritorious Service Medal; British War Medal; Victory Medal.

There was more than one "swagger stick"! 

The collection of Cec's preserved uniform items.  His "Warrant Officer" badge is displayed on the sleeve of his tunic. 
The "three blue chevrons" represent three years of overseas service. 
The belt with diagonal brace is called a "Sam Browne" belt and was another badge of rank.

Even for groundcrew, a flying helmet was essential to protect from the frigid slipstream in open cockpits when flying as a passenger.
A common practice was for mechanics to be taken up on the "test flight" after making repairs to an aeroplane.

The wood for this box came from the scrapped propeller of a Bristol Fighter aeroplane.
Such propellers were expensive and beautiful precision-laminations of fine timbers, but were often subject to damage in service.
(3AFC often used scrap RE8 propellers as grave markers, trimmed down to a Christian "cross" shape.  The "Red Baron" received one.)

French-made field glasses.

One of Cec's photographic collection, a rare view of 3AFC's first operational aerodrome on the Western Front.
The accommodation is in corrugated-iron 'Nissen Huts'.  The camouflaged canvas structure is a small French-made "Bessonneau" hangar for the aircraft.
[The word "hangar" itself means "shed" in French.]

Cec kept a remarkable collection of original WW1 "trench maps".  These days this information is available digitally, matched to modern-day satellite photos on sites such as Trenchmapper.

Sports behind the lines in 1917!  This is just after 3AFC arrived in France.

3AFC had expert photo-developing facilities, due to their ongoing photo-reconnaissance work, so the Squadron was also able to create plenty of "portraits".
[9th November 1918.  Cec is very smartly turned out after promotion to "Warrant Officer".]

"Regimental Sgt Major" was an honorific that put Cec in charge of all 3AFC parades, etc.  [Dated: Armistice Day 11-11-1918.]

Pals.

AFC Xmas Card 1918.  Because of the speed of mail-ships at the time, these would have been despatched to family and friends in Australia around September 1918.

Programme from a London reunion dinner for 3AFC, while waiting for shipping home.

After the Armistice, 3AFC moved to winter quarters near Charleroi, Belgium.  They operated an "Air Mail" service between the dispersed units of the Australian Imperial Force in Europe, including to Cologne in Germany, where 4AFC were serving "occupation" duty. 
Judging by his preserved photos, Cec obviously had a "passenger flip" in the mail-plane!

Cec in 1919 after returning to Adelaide.  [His extensive and rare collection of photographs of the AFC's return on the Kaisar-I-Hind is exhibited on a separate web-page.]

Cec's post-war garage in his home town of Minlaton SA.

Below: Both sides of a postcard from pioneer aviator Harry BUTLER to Cec.  (A souvenir of the first crossing by air of St Vincent Gulf SA.)

Circa 1919 - the wing is that of Harry's red Bristol Monoplane. 
The identity of the elderly man is unknown, but he DOES resemble Harry, so maybe a rellie!

Memorial Plaque to Cec at Minlaton SA.

Matt now has his great-grandfather's treasures displayed in Adelaide in a cabinet of WW1 period design.

Memorial Stone.  Cec died 27 May 1944.
