About the book mr. Khorasani "Arms and Armor from Iran". I think that mr. Khorasani do not know the Russian language and do not read books by Russian authors published in the 19th century (By the way, this does not make the book mr. Khorasani less good. This is an interesting book. Although, it is like any book have controversial moments). This is normal. You can not know everything. Very few Russian books in the 19th century was translated into English and French. Although the Russian travelers, merchants, officers and diplomats were in the 19th century in Persia more often and longer the British and especially the French (it's easy to explain - Russian a little closer to Persian than the UK and France).
I did not write "everywhere in Persia in the 1850s did a lot of years of wootz blades." I'm talking about the fact that the manufacture of blades from wootz seen Russian in Tehran. And what they said casually, not seeing it as something wonderful. That is, it was for their not strange and startling.
Until the 1880s, demand for the wootz blades in Central Asia - very high. And apparently, the main demand was for the blades of swords. Why until 1880s? Because only in the 1880s Russian troops seized the fortress Turkmen Gkok Tepe. It was only in the 1880s Turkmen tribes (Tekins) were disarmed. Turkomans were not able to do wootz blades themselves and bought them in Persia (in mid-late 19 centry).
It makes sense to write in the blade, which is made in the 19th century: "Made in 1750, the year." This makes the blade more valuable. It makes no sense to write in the blade, made in the 18th century or early 19th century: "made in 1870".
Regarding damask in India in the 19th century. R. Elgood book - an excellent book. But I think in India is not only the arsenal in Jaipur ....
Also, as modern collectors, any Raja had to appreciate more older blades (IMHO)
