This restoration was performed by Col. Ed Lucas, Old Dominion Squadron of the Confederate Air Force. Thank Ed for the opportunity to sit and operate this marvelous restoration and also for the chance to take these photos for all of my modeling mates. Okay folks, here a little up close and in person for those of you anxiously awaiting those late modeled B-25 from ACCURATE MINIATURES or maybe tinkering with that old Monogram kit you had in the attic. Col. Lucas told me, that painted areas (seat, etc.) of the turrets used in USAAF and later USAF aircraft were finished in an anodized bronze green, whereas painted areas of U. S. Navy aircraft were finished in neutral gray and later dark gull gray.
This view shows the turret from the port front.
Here's a view from the rear. The oval placard
is on the rear of the gunner's seat.
A close up view of the Plexiglas bubble from the front
showing the gear mechanism and ammunition feeds.
This close up from the rear shows the gun sight,
switch control, and more of the ammunition feed.
This close up of the lower port rear shows
the seat and port side electrical seat up.
The canvas bag is for used cartridges.
This shot shows the electrical system on the starboard side.
This final shot shows the inside looking up. The aluminum ammunition
canisters are visible, as is the control yoke and switch control.
The oxygen hose is seen in the left hand side of the photo.
I wish I could have taken photos whilst sitting in the seat and operating
this beauty, but you wouldn't believe how tight it is in there and the camera
just didn't have the field of view nor depth of field for such.
