Yup, and for texture, you gotta use their Client stuffs too.
If you have english patch for the tta3 client, and Those weapons comes in english names, than,
Convert IT0.ull, IT0ex.ull, IT1.ull, IT2.ull and IT3.ull to 0.bin, 0ex.bin, 1.bin, 2.bin, 3.bin repectively.
Use NPC2TXT and convert them to text files.
Find that item in the text files, see its Code, and generate using GM command, @ITEM?ITEM_CODE: in chat mode.
Rename 0.bin,0ex.bin,1.bin,2.bin and 3.bin to 0,0ex,1,2,3 and put in item folder of your zs/zonedata.
Use tta3 client, and vola your will have your 10.5, by hit and trial find out the texture files and overwrite in your own client and there you got your 10.5 in your client
