That's actually a damn good question. Was the Zimmerit applied before such fittings as stowage bins and other accessories were installed during production or afterwards? 

Yes, I found numerous wartime photos in my references of zimmerit all the way around the back of the turret (if this is what you mean), and underneath and behind the stowage bin. It looks as if the zimmerit was applied completely around the turret prior to installing the stowage bin. This was only made obvious by close-up photos showing the stowage bin removed or destroyed.

On the other hand, if your question meant to ask if there was zimmerit applied to the back of the stowage bin itself, I found no evidence of this in any of the photographs I looked at so far. I think the stowage bin was too flimsy to bother applying zimmerit.

Hope this helps.
