I have put a Sperry B-17 top turret for sale. Part of the proceeds will go toward our PV-2D Harpoon project so please spread the word to anyone who you think might have the slightest interest as we need as much as we can get. The more money raised from this sale the more the Harpoon gets so email this link to all who may be interested or at least anyone who might be able to spread the word for us.
http://www.ebay.com/itm/181119277704This is a display ready turret that rotates and elevated by hand. It isn't a complete turret as you can see but its the upper portion of the original ring casting, gun platform and dome mounted on a roller bearing ring gear so it moves very smoothly and elevates easily by hand. The turret is mounted on a three legged stand but it can also be easily mounted in a flying aircraft with some straight forward work to make the installation airworthy.
The Sperry upper is the hardest turret to find today so it is quite sought after by turret Geeks, collectors, museums and B-17 owners. It is a fact that there are more surviving B-17's around today than there are Sperry upper turrets. Most of the turrets on flying B-17's today are original, reproduction or fiberglass domes only with guns that are fixed in place. I believe that none of the turrets in B-17's flying today can rotate or elevate.
This turret has a factory original dome complete with its WWII Olive Drab paint on the outside and the Army Bronze Green paint on the inside still intact. It is a true museum piece as it was still sitting in the factory that made it in WWII. Thanks Albert for saving it! This dome and the gun platform are both unrestored and are original just as they were made. I did replace the center plex of the dome as it was missing when I got it but it has been replaced using the original hardware except for five screws and nuts.
What is cool about this type 6 dome is it is painted OD green which means it is from an early model B-17G as the later natural metal aircraft had domes that were painted silver.
Here is a YouTube video of my daughter taking the turret for a spin:
