Stephan, Thanks very much - all very useful.
Hi all, meanwhile some more info appears regarding this ACADEMY release. It is in fact a re-box of the ancient ITALERI Leopard with no changes and no new tool at all. I am a bit disappointed, that is a lost chance. So Mr. Tamiya: come up with a decent early Leopard 2. It has the 40th anniversary in German service… 
Bummer… I was getting excited there… 
Yes mate, have to make only a few modifications to finish as Turkish 2A4.
Here is my work on Meng’s kit. Take a look and if you have any questions; feel free to ask.
