Hi!
Ok the knoweverything boy Panzerknacker craked in 5 seconds my question about thing hanging from Pz. I.
Lets test him again. 
What is that hanging on this Pz. V?

Too easy!
It’s a ladder. 
Ha…I wont say the answer, just that this system is very used in Argentina…today. :rolleyes:
And no I am not talking about ladders.
Mr.SmartGuy!
Hereis a similar thing…
You are absolutely not indebted to do that, my dear Mr. Panzerknacker – if I remembered that well, this specific topic was already fairly and squarely explained by you!
Due to severe gasoline shortages Germans were forced to use bottled gas, as all available liquid fuel has been supplied for the operational combat units. Therefore direct answer to your undeniably ingenious question, my dear Mr. Egorka is: Pressurized gas equipment, more precisely high-pressure reservoirs. 
You will be able to find another picture here:

BTW: those previously presented by you are very good ones. Thanks!
It is.
There is 1,5 million of cars rolling with that system in here , high pressure natural gas ( Erdgaz in ww2 germany)
I think this contraption was used in training only.
One bullet would be enough to make it explode, so they were not as crazy/desperate to send these to the front. The color plate of the panther in previous link clearly says that it’s from Eisenach, which was a panzer school/training center.
Nah, it’s actually Nitrous Oxide injection for the various Wehrmacht boy racers
strange, it is possible to destroy a tank with a single bullet directly to the gas tube. They were no protection.
