It. ..,..,..;. By DOUGLAS B. ARMSTRONG First British Glider Post NONE of the published accounts of the Light 'Plane Trialsat Lympne, October 8 to 13, seems to have referred to the special mail flight which took place on the last day of themeeting. About 100 letters, enclosed in special souvenir envelopes, were carried by Mr. "Jimmy" James in theA.N.E.C. machine that put off from Lympne at 3 o'clock on the Saturday afternoon, the mail-bag being dropped byparachute at Hastingleigh, the farthest point on the course, a few minutes later. The letters were conveyed by specialcourier to the Hastingleigh sub-post office, and thence despatched to their destinations. In the right-hand cornerof the envelopes is an oblong grey label bearing a \\d. postage stamp, and the Hastingleigh postmark, in conjunction withthe declaration " Carried by MOTOR GLIDER from LYMPNE to HASTINGLEIGH." Twenty of the letters bore in addition thepersonal autograph of the pilot, and one of these was ex- hibited with the winning machine at Selfridges last week. Aero-philatelists will be keen to add this interestingsouvenir to their collections of British air post covers. More French Semi-Officials ANOTHER set of six semi-official air post stamps was issuedat Rouen on September 23 in connection with the Aviation Meeting in that city. It is composed of the values 25, 50,75 centimes, 1, 2, and 5 francs, somewhat crudely lithographed with a vignette of a 'plane descending. A similar issue ofstamps were created at Amiens on the occasion of the aviation meeting held there on October 7. We are indebted to ColonelW. H. Moffat for sight of flown cover bearing five of these stamps. The main feature of the design is a vignette of threeaeroplanes manoeuvring in the ether enclosed within a laurel wreath. Beneath it, in the centre, is a white shield containingthe figure of value, whilst the inscriptions read : " Service Postal Aerien " at the top ; " Amiens, 7 Oct., 1923," on eitherside at the foot. Designed by Henri Rudaux, these stamps are lithographedin large upright format in the following varieties : 25 centimes, yellow-green ; 50 c, blue ; 75 c, carmine •; 1 franc, blue-green and carmine ; 2.50 fr., orange and dark blue. The special postmark is lettered : " AMIENS AVIATION—7.10.23,"and the flown covers bore a pink label with the words " PAR AVION " printed in black. German Aero-Philatelic Club • BY courtesy of Mr. W. E. Hughes we learn that: "At anumerously attended meeting in Berlin on September 12 last it was unanimously decided to form an aero-philatelic societyunder the title of the ' Aero Philatelik Club von Deutschland ' (A.P CD.), for the study of air posts. The following officerswere elected : President, Carl Count de Matzenau, Berlin- Grunewald ; Vice-President, Bankdirector Hans Ueberall,Chemnitz ; Secretary, Dr. Arno Marquardt, Berlin ; Treasurer, Herr C. Butow." " . , . •. Novelties FROM Mr. Francis J. Field we have received an interestingflown cover, used in the Copenhagen-London service and franked with a number of contemporary Danish postagestamps, cancelled with a special air post-mark lettered " KOBENHAVN—LUFT POST," and dated 2.10.23. The same correspondent submits an envelope bearing aset of current Swiss air stamps obliterated with a souvenir cancellation reading " FLUGTAG—CHUR 30 Sept. 1923." Theseletters, we understand, were conveyed by air from Chur to Dubendorf on the one day only. ANSWERS TO CORRESPONDENTS E. V. T. (Matlock).—There is very little value attached tothe London Windsor souvenir cards. They usually change hands for a few shillings each. NOVEMBER 15, 1923 SOCIETY OF MODEL AERONAUTICAL ENGINEERS A LARGE number of members attended headquarters withfriends to hear Mr. B. K. Johnson's lecture. It was very much appreciated by all. The lantern slides gave an excellentidea of the work done by the members during the past twelve months. A hearty vote of thanks was given to Mr. Johnson.Mr. E. Shanly kindly assisted with the lantern. On November 22 at 7.30 p.m. a lecture, with demonstra-tions, will be given at Headquarters by Mr. W. E. Evans on " French Polishing." An important announcement will be made by the Competi- tion Secretary next week. A E JONES, Hon. Sec.
