Check out this intriguing short 13 minute video by Tested.com about a professional WWII turret restoration expert.
Sorry for any advertisements that may show in the video.; it’ not my intent to show them, but it’s sadly the cost of interesting online media in the 21st century.

Great find. Thanks for sharing.
Any contact information for Mr. Bieser? My grandfather was a tail gunner in B24 shot down over German occupied Belgium April of 44′.
I am working with an author in France trying to identify an aircraft partially from pieces of turrets, if you have an email for Mr. Bieser it would be much appreciated.
Thank You for the story and continued interest in WWII history.

John,
I can’t seem to find his contact info. BUT you could try contacting him on LinkedIN. It looks like he has an account. Best of luck with your search – it sounds interesting!

Thanks Again,
