AERONAUTICS

In a letter to Gertrude Tomkinson of 10 June 1934 (offered separately as part of an archive relating to the loss of HM Airship C8) Evans states that he was 'stationed at Kingsnorth [Airship Station] near Hoo for sometime during the War [...] but not drafted there before the end of 1916'. In another letter to the same recipient on 24 July, he mentions that he is writing an 'account of the work of the Airship during the war'.

The Bristol Aeroplane Company was an early and important innovator in the field of aircraft design and development. Four variants of its Titan engine (I, IIF, II Special, and IV) were produced in 1928. The present brochure and photographs are contained in a large manila envelope, with 'The "Bristol" Aeroplanes' printed in green on front. The photographs are all in very good condition, and all measure around 18 x 23.5 cm. The brochure is 4pp., 4to, printed in brown on a bifolium of cream paper. It is in good condition, with a little wear and creasing.

The four items in good condition, on lightly-aged paper. Letter to 'Mr. Bourne': 1p., 8vo. Replying to a letter from Bourne, he states that he will be 'very pleased to serve on the proposed "advisory board", provided that no financial liabiltiy is thereby incurred by me, & that no great amount of travelling is involved.' He concludes with the news that he is 'still busy on a hypersonic transport aircraft especially designed to take "containers".' The two photographs are both in black and white.

26pp., 12mo. Stitched. In remains of original printed wraps. On aged paper, in chipped wraps, with several leaves loose. An important work in the history of eronautics by one of the great experimental physicists of the nineteenth century. Excessively scarce: no copy of this offprint in the British Library or on COPAC. 'In this lecture Rayleigh discusses the method of calculating the mechanical forces on a plane presented obliquely to a current of air, so far as this can be done. At best, the calculation is very incomplete.

1p., 8vo. A fragile piece of ephemera, on aged paper, with wear at head (not affecting text). The notice begins: 'For several months past the Council has had under consideration the question of the Society's finances since it has become apparent that our annual income is insufficient to ensure a continuous and regular flow of publications.' References follow to 'donations from private members', an 'enforced summer recess', 'the acquisition of library shelves, desks and other fittings'. Two reasons are given in justification of the doubling of the 'Fellowship subscription'.

Sepia photograph of airborne balloon with a tangle of guyropes and mass of people beneath it. Hangars in background. The airship pioneer August von Parseval (1861-1942) worked in partnership with the engineer Hans Bartsch von Sigsfeld and the businessman August Riedinge. The "Dragonballoons" (Drachenballone), which he designed for military observation, are predecessors of the present-day blimp.

In poor condition: torn and stained and laid down on a piece of thin card, and with the extremities of the margins chipped. Loss to top-left and bottom-right corners. The loss to the top corner includes a corner of the print (roughly 40 x 20 mm), but this only features the sky.

Historian of aviation (1909-81) at the Victoria & Albert Museum, London. Eight items, various formats. Very good. LETTER ONE (two pages, octavo, 14 January 1949, on V & A letterhead): 'As a very new fellow of the Society I hesitate to burden you with reading the enclosed [an article on 'Father Gusmao: the first practical pioneer in aeronautics', not present], but I thought there might be some chance of its appearing in the Journal. It is too historical for the Roy. Aeronautical Society's Journal and too aeronautical for the others, so I am stuck!

Printed wraps, illus.., fold mark mainly affecting covers, mainly v.g. NO estimate or price lists
