I mentioned in my last Jottings that a further part of the Walter Grob collection was going to be sold by Corinphila Auctions at Zurich, Switzerland.  The sale took place in November and many rare items sold at high prices including this Scout's Post during the Warsaw Uprising of 1944.  The description reads "Folded letter sheet addressed to Hanka Kokoszka in 4th Company, bearing red 'AK' Field post stamp without denomination issued on 3 September, 1944 and tied by the scarce violet circle handstamp HARCERSKA- POCZTA-CZERNIAKOW with Scouting Movement’s Lily (Gryzewski type 5) and boxed Censor mark CENZURAOWANE (No.14) in black and eagle handstamp PIECZEC LISTOWA alongside.  Broken folds carefully reinforced with hinges, a fine and possibly unique usage on a field post stamp.  Certified by Petriuk (2017).  In September 1944, the Scout Field Post and all its workers were incorporated into the Home Army, which is when the "Scout Post" changed its name to "Field Post".  On 5th September, postage stamps were introduced - a different colour for each of Warsaw's five districts.  The postal service ceased operating on 3rd October - the day that Warsaw surrendered".

Most of the known Scout India Rocket covers and other ephemera from the Scout & Guide Jamborees held in 1937 were also on offer, but recently there has been a number of sales of the this material, notably in Israel.
Therefore some of the covers were unsold, but as always there was a market for the Girl Guide cover, which made treble the estimate.
Here is the catalogue description "1937 (March. 2): Girl Guides Rally Bengal, Propaganda Rocket No.7, envelope franked with India 9 pies stamp cancelled by Calcutta cds. together with imperf. vignette in orange tied by purple "GIRL GUIDES RALLY BENGAL carried by Propaganda Rocket 2-3-37" cds., with endorsed 'This rocket was fired by the World's Chief Guide Lady Baden-Powell' in manuscript, signed by Stephen H. Smith.  A fresh and rare envelope, only 30 envelopes flown".  Note the spelling error of the word "Propaganda".

Still in Switzerland, during December 2017, the auction house David Feldman sold the Egyptian 1956 Second Arab Boy Scout Jamboree set of three stamps in imperforate blocks of four with margins.  I do not know how many sets of these stamps were issued imperforate, but when Feldman sold pairs in December 2011, he stated "...only 50 pairs are known to exist, and as such these are scarcer than the desirable souvenir sheets, where 1037 were sold".  Our own SGSC catalogues complied by Alan Nicholson in 1965 stated that there were 1000 sets sold imperforate, but have no idea where he obtained this information.  Estimated at $4600, the blocks sold for €3600.

Only occasionally do we see 1929 Boy Scout World Jamboree registered covers for sale, but recently this one was offered on eBay at a starting price of £1100, but it did not sell, mainly because it was a window envelope in not that brilliant condition.  I have been in contact with the seller, and he informs me that he purchased this cover at one of our club auctions in the early 1960's.  To date nearly 40 registered covers from the this World Jamboree have been recorded, but virtually half of them are window envelopes.
