My first fatal mistake.
When I closed the top of the turret, all of the tabs were glued at once with the results shown in the picture.
I should have glued the white tabs, one at a time to keep them under the top of the turret.
Did the same thing with the rear of the hull and had the same results.
Good enough for a Wargame but not good enough for a build thread.
I will need to build a second turret and attempt to do a better job.
The fenders and tracks are not glued yet.
They were only set against the hull for the picture.
