What an interesting topic Anandalal, and I had forgotten the 2005 entries.
The subject on leather cannons goes back to the beginning of the 17th century, and though these innovative artillery became notoriously known from the armies of Gustavus Adolphus of Sweden, it was apparantly created in Switzerland prior to that use.
Apparantly these were copper tubes reinforced by ropes and leather alternatively...the problem with them was that these materials did not dissipate heat and after firing, especially consecutive shots, the barrel would become red hot. This would not only deform barrel but accidental ignition of powder was a danger.
In "The Army of Gustavis Adolphus" Vol.II (R. Brzezinski, 1993, p.17);
"...the leather cannon was superceded in 1629 by a weapon that did not have the same tendancy to overheat and burst".
I am wondering if these might have been props intended to present the image of artillery to attacking forces? They seem to represent the profile of European artillery down to the cascabel, but are there touchholes to ignite the charge? It seems odd that the somewhat legendary leather cannons of Adolphus would be known in Nepal, and be imitated, as well as it would seem fortunately not actually fired.
Would Chinese or other Asian groups have used leather artillery? and would they have looked so much like European superficially?
Best regards,
Jim
