This is a set of 12 photographs of Army teams from the Army Survey Regiment, Bendigo and the Army School of Transport, Puckapunyal attempting a world record playing indoor cricket, at Seymour Victoria from the 31st of January to the 5th of February 1986. The following article appeared on the back page of the ARMY Newspaper on Thursday 6th of March 1986. 'INDOOR CRICKET RECORD SMASHED. ARMY TEAMS from Puckapunyal and Bendigo recently played indoor cricket for 124 hours to set a new world record. The two eight-man teams, from Army School of Transport and Army Survey Regiment, broke the 120 hour record set by Corrimal High School, NSW earlier this year. Organiser of the event, Capt Marty Alsford of AST told ARMY the teams had played 107 games, scoring 15,000 runs in their chase for the record. "The rules allowed a five-minute rest break every hour which could be accrued, so we played for 64 hours straight then had a five hour sleep. "When everybody got up and went straight back into the game with no grumbling, I knew we had the record," Capt Alsford said. The event was held at the Seymour Indoor Cricket Centre, an iron-roofed building with no air-conditioning, and all players had to battle the effect of the stifling heat in addition to fatigue. One player dropped out through exhaustion, but this did not prejudice the record attempt as the rules permitted each team to lose a player who cannot return to the game nor be replaced. The Army teams' effort are now awaiting recognition by the Guinness Book of Records. During the marathon event, the soldiers raised money for Legacy, through sponsorships and a raffle. At the time ARMY went to press, the final figure was not available.’ Army Survey Regiment Routine Orders Part 1 Issue No 16/86 Notices on Page 7 stated: ‘World Record Indoor Cricket. 1. Congratulations to the following members for their successful attempt on the Guinness Book of Records, Record for continuous playing of indoor cricket: John Whaling, Peter Ball, Brenton McDonald, Per Andersen, John Anderson, Brian Fauth, Brett McAllister and Daryl South. 2. Our team, playing a team from Army School of Transport at Seymour played continuous Indoor Cricket for 124 hours, beating the existing record by 4 hours. During that time the two teams amassed a total in excess of 16,000 runs. 3. Congratulations also to Peter Ball for picking up the Trophy for the most outstanding player during the record attempt.’This is a set of 12 photographs of Army teams from Bendigo and Puckapunyal attempting a world record playing indoor cricket, at Seymour Victoria in February 1986.

Photo of Bluey Truscott. Squadron Leader Keith William (Bluey) Truscott was regarded as one of Australia’s most well known WW2 fighter pilot aces. He was born on the 17/5/1916 and died over Exmouth, Western Australia on 28/3/1943 in an Aircraft accident whilst on duty. He initially trained under the Commonwealth Empire Training Scheme In Canada at the beginning of WW2, and later on was posted to Number 452 Squadron England where he flew Spitfires over Europe. He was awarded the distinguished Flying Cross in 1941 for his Air action and bravery. In 1942 he was further awarded the DFC Bar for further outstanding Air action and bravery. He returned to Australia and commanded number 76 Squadron who undertook duties in Papua New Guinea, specifically Milne Bay. When with 76 Squadron they largely flew Kittyhawks. There is a club named after SQN LDR Truscott, called the Truscott Club, at Airforce Base Darwin. There is also a decommissioned WW2 Airfield in the Kimberley’s called after him ( Truscott Air Base). Truscott has more recently been called Mungalu-Truscott Air Base as it is now owned by the traditional people of the Wunambal Gaambera. The Airfield is now used for commercial and private flying and is heritage listed under the National Trust of Australia (W.A.) due to its historical significance relating to WW2 and the remaining artefacts that are still in place presently. Bluey Truscott was also a well known Australian Rules Football player prior to WW2 having played for Melbourne.

A porthole, sometimes called bull's-eye window or bull's-eye, is a circular window used on the hull of ships to admit light and air. Though the term is of maritime origin, it is also used to describe round windows on armoured vehicles, aircraft, automobiles (the Ford Thunderbird a notable example) and even spacecraft. On a ship, the function of a porthole, when open, is to permit light and fresh air to enter the dark and often damp below-deck quarters of the vessel. It also affords below-deck occupants a limited view to the outside world. When closed, the porthole provides a strong water-tight, weather-tight and sometimes light-tight barrier (not in the case however). A porthole on a ship may also be called a side scuttle (side hole), as officially termed in the International Convention for the Safety of Life at Sea. This term is used in the U.S. Code of Federal Regulations. It is also used in related rules and regulations for the construction of ships. The use of the word "side scuttle" instead of "porthole" is meant to be broad, including any covered or uncovered hole in the side of the vessel. This porthole is a useful demonstration of naval technology to give people an insight into life at see. Small windows such as this example could be all people would see on long see voyage across rough seas. Commanding officers scuttle made of brass with glass opening windowmaritime technology
