Help for ID - Afghan musquet

[LPCA]

Bonjour,

I go on with my research on ID for my study on oriental firearms....to come on BLADE.

Here is an afghan musquet : Djezaïl or Jezaïl.

Please see details on http://blade.japet.com/B-afghan.htm

2 questions in this quizz:

1- on the silexlock, there is a word IODER.... can someone tell me what is its extensive meaning (indian....)

2- on the barrel near the fireblock, there is an inscription that seems to be in arabic characters.... what does it means??

Thanks a lot for your attention.
