Amsler Polar Planimeter [Measuring the area of complex irregular shapes/ boundaries] c1910

Plush-lined fitted case some 12” long contains a polar planimeter invented by Swiss mathematician Jacob Amsler. All in very good condition and working order.

The instrument was a revolutionary change from the complex Cartesian system base instruments used before. This device uses polar co-ordinates.

With this device two arms are connected with a pivot both arms moving around the anchor. As the pivot moves back and forth it traces an area whose net measurement is zero. The means that the area traced by the tracer point exactly equals the area of the closed curve. The area is equivalent to 2pi X the product of the length of the tracer arm, the radius of the counting wheel and the number of revolutions of the counting wheel.

In more modern times mathematicians apply “Green’s theorem”.

Amsler’s radical and very useful new design

Australian Ashes Cricket Team 1934 [Bradman, Woodfull, Ponsford et al] Unusual Original Advertising Memorabilia.

Significant size would frame and display nicely – fragile so handle carefully. One of the most usual pieces of period advertising we have come across.

With the strong message “Well laundered sports wear gives confidence” we are told to “Send your cricket and tennis flannels and Ladies sports frocks” for proper laundry treatment to provide the above mentioned confidence.

Nice image of the team, not all in baggy green and a strangely suited L Darling.

The 1934 Ashes were held in England and Australia won off the back of some solid batting by Bradman and Ponsford. England started well wining the first test – Verity took 15 wickets. The next two were drawn but Bradman/ Ponsford scored a partnership of 388 at Headingley and 452 at the Oval to take the urn.

Dimensions 50cm by 25cm, the odd wrinkle as one would expected but generally in good condition – take care of it!

Bradman 1934 Ashes treasure – how has it survived?

WWI Copper Flask in Original Bespoke Leather Carrying Case [Super Condition] – Captain McCracken

Captain Kenneth Mills McCracken was a member of the Royal Field Artillery attached to the Royal Flying Corps. His service record covered the entire of WWI 1914-1918 so likely one of the few that survived his dangerous role.

Born in 1895 and from Newcastle-Upon Tyne he was a medical student at Edinburgh University when World War One broke out.

The Royal Flying Corp was the air arm of the British Army at the start of the war and it was not until 1918 that it merged with the Royal Naval Air Service to become the Royal Air Force.

McCracken’s record shows that he was skilled in artillery observation; so, he was likely an aerial observer or photographer. At the beginning of the war their photographic efforts were very primitive almost hopeless until 1915. By 1918 they could make decent images from 15,000 feet and had a team of 3,000 people analysing the results. The Royal Flying Corp didn’t get into aerial combat until the later part of the war.

The item is in great condition. The full leather casing is 25cm by 10cm, stitching perfect – nicely embossed with McCracken’s details. The copper thermos has a ding but is a solid actually useable item. The screw on top is undamaged and goes on and off easily.

Special WWI Item in great condition with interesting provenance

White Blackfellows – Charles Barrett

Published in 1948 by Hallcraft, Melbourne. Octavo, 261 pages, well illustrated. A very good copy in a nice albeit chipped dust jacket.

We recognise that the title of the book is unacceptable. Accept the book though for the history within. Sixteen different histories from all over Australia. Many of these have inspired other works – Patrick White etc. And, quite a few appear in longer form within the Voyager collection – but in no other place do we have a balanced presentation of so many.

Mrs Fraser, William Buckley, James Murrells, Barbara Thompson etc and the dubious Louis de Rougemont

Robert Louis Stevenson – Memories – 1926

A very unusually presented biographical work on Robert Louis Stevenson published by Peter Davies, London in 1926. Not a first printing but extremely scarce regardless.

Tall slim octavo, card covers with affixed wrap around picturesque cover with yap edges. Internally twenty five pages of tipped in images from original photographs with narrative opposite. A mixture of the people, mainly family, in his life … his life in Scotland and in Samoa [which probably saved him from ill-health] and his magnificent schooner “Casco”.

Some age to yap cover, internally pretty good, gift inscription on front ends.

An unusual piece of R.S.L. ephemera, near a hundred year old and of an emotional quality
