AIR POST STAMPS By DOUGLAS B. ARMSTRONG. Russian Aero Stamps IT appears that the mysterious new Russian air post stamps were in readiness for issue towards the end of last year, but were withheld owing to suspension of the air mail service during the winter months. Meanwhile a new gold standard currency had been introduced, necessitating alteration of the values originally indicated in paper roubles—hence the surcharges. The unsurcharged varieties are really therefore in the nature of essays, and as such are extremely scarce. The total printings of the surcharges are said to be 450,000 of the 10 kopecs on 5 roubles, 950,000 of the 15 kopecs on 1 rouble, and 1,450,000 of the 20 kopecs on 10 roubles. A fourth value has now made its appearance, viz. 5 kopecs on 3 roubles blue, of which there are a like number to the 10 kopecs. Russian 45r. Air Stamp IN the course of some interesting notes upon the " Air Post of Soviet Russia," cpntributed to the Postage Stamp Mr. G. H. Bigsby comments upon the scarcity of the Russian provisional aero stamp of 1922. " Only very rarely," he writes, " does one come across a flown cover franked with the special 45r. aeroplane stamp (overprinted with the out line of an aeroplane in red). These stamps were issued on November 8, 1922, in honour of the fifth anniversary of the Soviet regime. The total issue did not number 100,000 copies. Only very limited supplies were distributed among the different post offices throughout the country. In order to prevent speculators from buying up the entire stock the Soviet authorities took stringent measures, and not more than two specimens were sold to each applicant. But not withstanding these precautions the supplies of the 45r. air stamp were soon exhausted, and even in centres like Moscow and Petrograd none could be procured three or four days after they had been put on sale. This will not seem surprising when one realises the enormous dimensions of the country and the smallness of the issue. " A very small number of these stamps were utilised for the actual prepayment of correspondence sent by air, in view of the fact that at that time it was obligatory in Russia for all senders of such letters to hand them for prepavment to the postal official, who affixed whatever stamps he fancied— ordinary or special air post ones. It is safe to assume that not more than 3,000 or 4,000 copies of the 45r. air stamp were used for this purpose. Hence flown Russian air covers bear ing the stamp are considered rarities." More Swiss Semi-officials WE are threatened with an avalanche of semi-official air post labels in connection with Flying Days held in different Swiss towns. It seems probable that the epidemic is not unconnected with the high prices that are being fetched by similar issues of the 1912-13 period. The latest Swiss semi-official air post stamp hails from Romanshorn, where an international aviation meet appar ently took place on June 9, 1924. Of the denomination 30 rappan, it depicts a lake scene with hydroplanes in the air and on the water ; colours brown and yellow. Beneath the picture is the inscription " Internationales Schaufliegen Romanshorn Pfingstmontag, 1924." The stamp seems to have had no franking power whatever, and was not even can celled with the regulation postmark. Letters conveyed by air from Basel to Bern on a special flight on May 27, 1924, were prepaid by current Swiss air post stamps of the government issue, which were cancelled how ever by a special violet postmark inscribed " Flugpost 27.V. 1924 Basel-Bern." In addition flown covers were impressed with a cachet in blue lettered " Basel Muster- messe 27.V.1924 Flugpost Basel-Bern." 9ouvenir post cards showing a view of the fair and overprinted with a like inscription were also employed on this occasion. At Lausanne on May 29, 1924, a temporary post office v;as established on the 'flying ground at Blecherette for an international aviation meeting, and letters specially post marked " Lausanne Blecherette 29. V.1924 Poste'Aerienne " in black were forwarded on the following day to Geneva, Zurich and Munich per the air line " Ad Astra Aero."
