missing/hidden ltb files

HI. just wanna ask about REZ16 (crossfireph). In other countries it's not named REZ16 but contains the same files. So my question is, is this the only rez file that contains ltb for guns that are widely used for modification of reload, fire select etc. I noticed that some ltb files of guns cannot be found here, gatling gun and R93 T2 ltb files for example. Is this the only rez that contains ltb files for weapon texture modding?

You should find in directory Crossfire \ rez2 \ RF016.rez
