For some reason I have always liked the looks of the AEC anti-aircraft turret that was used on the Crusader tank and the AEC armored car. I thought it could work on my Zombie project. Originally I just intended to build it as it was in real life with twin 20 mm Oerlikon guns Then I thought it would look better with 4 .50 cal mgs, or at least different as I had 20mm guns on the "Churchill" turret. There are some other changes too, I never intended to build an accurate copy of the AEC. I intended for the mgs to rotate, but that's all. Then I got the urge to articulate the sights with the gun elevation and depression. Sometimes things get out of hand and I think I built the pivoting levers and linkage two 3 or 4 times before I got it workable...... not perfect ..... just workable. There's still some minor clean up and then the painting begins.
