Help to find o to Download Firmware

Hi, I need any Help to find or how to download an Specific Firmware for WE826-t2.
I need the OpenWrt AWF-5G V1.2 Powered by LuCI Trunk (svn-r10457) OpenWrt Barrier Breaker unknown.
Can someone help me where to find this version of openwrt? Or explain how to download a firmware from a router, because I have this version in one, and I could download it of the we826 t2 if it is possible...
I know that it isn't an updated version and it is old, but i need this version.
Thanks in Advance
