DBU Kraft Stoff filler cap
 

Hello, long time reader. This Forum has provided me with hours of reading, and great help. I am an amateur collector of Luftwaffe history. Recently I transitioned from signatures on postal covers to aircraft artifacts. It is daunting at the beginning, but I am trying hard to expand my knowledge.
I read the hints to new members, and that is my introduction.
Now that I can post I hope to help others as well.


I recently purchased this item, and I am stumped. After hours of reading I can not re-find the information I am basing my thoughts on what this is. I remember seeing a diagram of a drop tank that had an access hatch, and the filler cap under it. So, I figured this would be a good beginning with you all.
-It only has one hole on the ears for the retention chain.
-No vents.
-A makers mark I do not recognize.*see edit


If you could please help me with a link to the information, and how you found it, that would be very helpful.
Thank you

DBU....

Thank you for the reply. I know about DBU as a company. I may have posed the question incorrectly. Is this off a drop tank? If it was off a planes primary fuel cells it would have to be vented?

I have continued searching, but still need some help.

Here is a close up from one of the He219 cells at NASM Udvar-Hazy.

Thank you for your help. The image you've referenced you can tell it is vented, the holes are drilled through the cap. My example is not drilled out, leading me to believe it is off a drop tank. I can not find a good picture or in the manuals,but I am still trying.

Hello

Yes, your cap can come from a drop tank. Here an illustration :

Thank you very much, your bottom photo most definitely is DBU marked, and helps me greatly. What liter do you think that tank is?

The top photo is the "typical" drop tank filler cap, it looks slick no markings by maker.

At what point in the war did they change makers, and which example is earlier?

This is a standard cap for a standard airplane tank, used in many airplanes during WW II
