With the Bergepanther finished and the results of the poll on here and over on the Zone the vast majority of the votes where for the scratchbuild project so I've made a start
During this build I'd like you guys to attempt at guessing what it is
That type of plastic is fun to build and hard to paint as it peels off because the plastic is so soft. (Why its good as a pallet for the paint actually) Run some tests before you get too far and see if its going to work. If not change over to some Evergreen plastic sheets etc which is the same type of plastic as model kits and glues happily with standard model glue.
You may need a contact adhesive (in AU something like Tarzan's grip) that will hold the parts together rather than melting them together. The white glue may actually snap off the plastic like dried paint. See how you go though. Its very exciting waiting to find out what it is.
I've had to get a few measurements off Gary from the karl gerat transport carriers these measurements where the width of the carriers and the distance between the buffers so that may be helpful to you guys for guessing what it is
