JANUARY 17, 1924 BY DOUGLAS B. ARMSTRONG New Czecho- Slovak Issue NEW air-post stamps are heralded from Czecho-Slovakia in connection with the daily aerial mail service between Prague and Prezburg. which has been in operation since October 29th, 1923. They are to be of a definitive character, their face values being fixed at 10, 20 and 30 hellers respec tively. Presumably, they will be printed in the long- promised design, showing an aeroplane encircling the " Hrad- schin " Citadel at Prague. The first Czecho-Slovak aero stamps were issued on September 15th, 1920, coincident with the inauguration of a regular bi-weekly flying post between Paris and Prague, as well as from Prague to Warsaw. Special stamps were provided in denominations 14, 24 and 28 krones, representing the supplementary fees upon air-borne letters to Warsaw, Paris and through to London respectively. These were improvised by overprinting a crudely-executed aeroplane, together with the new value in abbreviated form, between two propellers, upon regular postage stamps of the 1919 series, with a vignette of the " Hradschin " ; in ted, black " or blue. In the first instance, they were issued imperforate, but a second printing placed on sale in the following March was perforated 13J. Errors exist surcharged on the wrong values, whilst the 28 kr. on 1,000 heller is known with the over-print inverted. On the suspension of the Paris-Prague service in October, 1921, these stamps were withdrawn from circulation. It was resumed in March, 1922, when for a time ordinary postage stamps were employed, and cancelled with a special postmark in violet ink, inscribed " Letecka Posta— Post Aerienne." The present issue of air-post stamps, surcharged on the " Art and Industry " stamps of 1920, was brought into use on May 15, 1922, in anticipation of the establishment of the Prague-Vienna-Budapest air line, which, however, did not actually commence operations until two months later. The overprint is similar to that of the first issue, except that the two propellers are so disposed as to obliterate the original figures of value, and the surcharges are in terms of " heller " instead of krones, viz., 50 100 heller, green; 100'200 heller violet; 250 400 heller, brown. Roumanian Irregulars AT a London stamp auction last month, £3 was paid for two sets of Roumanian stamps, purporting to have been used for air postage, but surrounding which there is an element of mystery. Roumanian postage stamps overprinted " P.A.R." (Posta Aeriena Romana) and " Posta Aeriena 1920 " were first heard of towards the end of that year, when they were alleged to have been issued by the Roumanian post office on the occasion of the extension of the trans-Continental air line to Bucharest. A circumstantial story was circulated to the effect that only 500 sets of either series had been printed. Inquiries on the spot, however, revealed the issue to have been an entirely unauthorised experiment on the part of an aviator more enterprising than honest, so that the stamps in question have always been regarded with suspicion by air post collectors. Air Stamps from Ecuador THERE does not appear to be any published record of an an-post service operating in the Central American Republic of Ecuador, although it is not unlikely that experimental postal flights may have taken place there at one time or another. This supposition is prompted by the fact that the existence of a hitherto unrecorded set of Ecuadorian stamps overprinted with the device of an aeroplane in red has recentlv been brought to the writer's notice. Can any reader or FLIGHT throw light upon this mysterious issue ? SOCIETY OF MODEL AERONAUTICAL ENGINEERS ANNUAL General Meeting will be held on Thursday, January 31, in the British Empire Room, Central Y.M.C.A., Tottenham Court Road, W.C. 1, at 7.30 p.m. Nominations should be received by the Hon. Secretary on or before the first post Thursday. January 24, 1924. Members are requested to take special notice of general rule No. 5. News has just come to hand that Mr. Tucker of Dulwich College was experimenting with a large glider, 10 ft. span, at Streatham, getting some interesting results. Mr. L. Lansdown, of the B.H.A.C, has been getting some glides from a new glider of over two minutes'duration. It is to be. hoped to publish fuller details later. A. E. JONES, Hon.
