[Q] Google Talk on an A13

So I bought 2 x All Winner A13's cheap off ebay (http://www.ebay.co.uk/itm/4003376921...84.m1439.l2649) so I could talk to my kids when Im away working using Google's "Talk" app. Turns out when the tablets arrived, the App wasn't installed. I cant find an APK file that works and Ive even tried instal GAPPs for 4.0.x with no luck.

My tablets are reporting themselves as:

Model Number: SoftwinerEVB
Android Version: 4.0.4
Baseband Version: 1.5
Kernel Version: 3.0.8+ android3@linux #80 Wed Nov 7 15:50:24 CST 2012
Build Number: nuclear_evb-eng 4.0.4 IMM76D 20121108

Please can you all tell me how I can find and install the "Talk" app which is installed on pretty much every main stream Android device out there but for some reason not on my A13's.

Thanks all and have a great Christmas everyone!
