Luftwaffe Drop Tank types?

[Alte Hase]

Hi all,

I'm trying to find out a bit more about the different types of drop tanks used by the Luftwaffe, particularly in 1944.It seems there were at least 4 types of 300 litre drop tanks, but despite seeing various designs in model kits, I can't seem to find any info on what types there were,what aircraft each type was used on, as well as photos or pictures of them.

Type B/C/D/E drop tanks were the main four used, all look pretty much the same. The B however did not have the relief on the bottom. Lots of pics on the net. There was one more also a cylindrical drop tank. These were also used on Fw 190D-9's:

This one happens to be attached to a G-12.
