Aziz,
Last time I was in Cairo, had some time and went off downtown to a very large gunshop that is notable in having a branch in Alexandria. Cannot recall either the name of the shop or that of the owner as it was about ten years ago.
Recognize that you are at risk of sharp practices, espcially where you have a prized good like the Francotte. Malesh. Perhaps there is a gun club in Cairo that might have some sensible members who can advise you. Otherwise, suggest you look at any Francotte guns on gunsamerica.com and on gunbroker.com and, also, invite any members of this board passing through Cairo to have a look!
Regards, Tim
