I found this pre-release screenshot of Codename 47 recently, it clearly shows the game was going to have grenades and a lockpick.
Other cut C47 weapons off the top of my head:
Silenced Hardballer
Shurikens (there is audio for this but it’d be a challenge to get)
Derringer (available via giveall cheat in HK and maybe elsewhere)
Blowgun (available via giveall cheat in Colombia)
Aphrodsiac (intended for HK)
Laxative (intended for HK)
Vacuum (available via giveall in Budapest)
I think there is other stuff but that’s all for now.
