All-India Scouts Jamboree — Delhi Rocket Despatch

In early February 1937 the All-India Boy Scouts Jamboree was held at Delhi. Alongside ordinary camp post and special cancellations, the Calcutta rocket experimenter Stephen H. Smith (secretary of the Indian Air Mail Society) staged a short series of rocket-mail firings on the jamboree grounds between 1 and 3 February.

For those flights Smith prepared private adhesive labels — classic cinderellas with no franking power — inscribed for the All-India Scouts Jamboree Rocket Despatch. They are imperforate, without face value, and were printed in three colours: red, green and blue (print runs often quoted around 2,000 of each). On flown covers and postcards the labels were tied by a special circular cachet of the type «All India Boy Scouts Jamboree Rocket Despatch / Delhi / 1 Feb 1937» (and related dates); many mint pieces also carry Smith’s signature or authentication on the reverse. Ordinary Indian postage was still required for the official post after recovery of the mail.

These labels sit at the intersection of Scout philately and early Indian rocket mail. They are not government Scout semi-postals (India issued no official jamboree postage set in 1937) but private vignettes created for a demonstration of rocket despatch at a national Scout gathering. As such they are sought by both Scouts-on-Stamps collectors and aerophilatelists who follow Smith’s long sequence of Indian rocket experiments (from the 1934 Saugor Island trials through the 1930s). Unused mint examples, reprints and signed flown covers all appear on the market; genuine flown material with the Delhi jamboree cachet is the scarcer form.
