Marinefahrprahm, A plea for help!

Hello everybody.
I run a small modelmaking business in England, called Speedline Models, we are associated mainly with RNLI Lifeboats.
However, we have started researching Marinefahrprahms. We will be producing a fine 1/72nd scale model in resin and at a later date, a 1/35th version for radio control.
I am hoping Marco Gurk reads this because his fine drawings were indeed responsible for our choice of subject.
It is good information I am after in lots of areas of the boats and if anyone can help, we would be most gratefull.
I look forward to your replies and thanks.

I don't understand what you are really looking for.
For Internet, the tag must be Marinefährprahm.

Many thanks for the help but I am actually quite well advanced with the project and have looked at all these before. I was hoping maybe someone may have photographs showing otherwise hidden information?
We are looking to make the type D (with two Tigers on board). Anything could help.
Thanks

Did you ask your questions on the websites more dedicated to the German army or to Axis as a whole (the latter also focused on the German army) ?

What about at a local millitary museam? Someone must have one somewhere.
