If you can wait a day or 2, I'll be to striping down my Tunisian Tiger's Turret and doing some work to it - I can post the pics of what I did while I'm working on it.
I've done 2 Tiger mantlet swaps so far, not a big deal if you get it back on straight (one of the reasons why this one has to come apart again is it went together crooked

) - see my Kursk Tiger in the 'combat ready units' thread
I've not tried the barrel stretch yet tho... :-\
