Panzer parts identification

[Admiraal]

Hello guys,
I found these panzer/vehicle parts recently on the Oder front in Germany but i need some help identifying them. I numbered them and added a 30cm ruler on the photo.
Part 3, 4, 5 and 6 might be from a T34 as i found a T34 track and track-bar nearby.
Part 7 is a large wrench but i'm not sure if its civilian or military. Does someone recognize it?

6 is a hand grease nipple-but I do not know whether Russian or German

I think you are right
When looking on Google for "Wehrmacht Fettpresse" some similar ones pop up for sale on Ebay. Maybe someone has some Panzer (tool) manuals they can check for it?
