Anyone has this kind of flash? If so, mail me!

(P.S. - I have 5 Galaxy flashes, whose versions are:
21162570 (untested)
21175500 (untested)
21182000 (untested)
21183000 (untested)
21183C00 (no Portuguese language)

Any info about these flashes, and/or language codes in flash names? Really appreciate your help...
