Thank goodness, I was going nuts. I read this question and started going through my 10 Tiger books, and couldn't find anything about aux fuel drums on the Tiger I.
But apparently you have the same problem ausf.
Like ausf said; do you have any pics you can post here.
Im not saying it didn't happen, Im just saying I can't find any reference about it.
BTW this is another reference question, would sure like to see that reference forum soon.
