I listened to a presentation from an American WWII Tanker at the Patton Museum.
He showed us the difference between the turret turning speeds of the Sherman and a Panther.
The Sherman turret was powered and the Panther turret had to be cranked.
He said they could get off a couple of rounds before the Panther could get them in their sights.
The Panther turret was hydraulic but turned slower than the Sherman.
The last model of the Panzer IV, the Panzer IV J, substituted a manually cranked turret for the electric motor in the H to try to speed production.
I was looking at the web page, love that statue with Willie by his side.
They have a fantastic museum here in Massachusetts in a residential area called The International Museum of World War II. It is a real jewel of a find. People don't know about it, and it has a LOT of stuff in it, and if you bring cotton gloves and they see you are careful, you can pick historic items up and hold them.
You actually have to schedule the visit in advance and sign a waiver and bring an ID.
It is in such a non-descript building with no windows, looks like a warehouse except it had an old beat up landing craft in the back and two 16" battleship shells by the door.
Some really interesting stuff. Hitler's little black address book with various phone numbers such as Berlin Gestapo Headquarters...Goering's luggage he had when he was captured. Very feminine...sky blue, with all kinds of brushes and mirrors in it.
But one of my favorite exhibits there is the bronze bust of Hitler that was taken from The Eagle's Nest (I think) and given to him, which he used as a door stop at his headquarters.
Every day when he took Willie out for a walk, he would pause there, and Willie would lift his leg and pee on the bust! When you see it in the museum, you can still see the corrosion stains...:)
