He-177A-6
 

I notice in the news from Nurnburg that Revell's new variant of their He-177 kit is an alleged A-6, which the prototype model on display showed to have a 4-gun tail turret. Did this variant ever see actual service or is RoG veering off into Luft 46 territory? Is there any reason to think the A-6 should be more associated with the Hs-293 than the A-5?
