[Q] help? topic

Hello I own a Samsung galaxy SIII GT i9300 running nightly build PAC man ROM 4.4.4. I deleted my stock backup on cwm thinking that I wouldn't need it but I'm getting a upgrade to the LTE version (GT i9305) now and I can't find out which model I am for stock firmware to sell this on, it doesn't say in settings and dialer doesn't work, and I need stock to sell this on. Is there a working ROM on all international's? I'm a noob at this so sorry if this is already answered or its a stupid question

Thanks in advance!
