Hello,
Really Thank you all for your comments !
Thank's a lot Kronckew for the details about make/remove a sword hilt !!!
For the model, I thought too when I bought it that it was a french model inspired by the Egyptian campaign of Napoleon but I found two stamps and they are Austrian Silver Hallmarks ( 13 lot ) ( Really not easy to do a good picture of it !! )
that's why my ''eared'' eagle or camel turned to the idea of a griffin sometimes seen on Habsbourg family coat of arms and Vienna's statues
For the stamps, What is interesting is the date,
really old and well preserved item: 180(5?) if I'm right
( the last number is difficult to read ).
if 1805 it coincides with the Austerlitz battle between Napoleon and the Russian and Austrian empire ( a full circle

)
