Can anyone point me to a guide for early markings as applied to Bundeswehr vehicles?

I have identified the Panzerbaer site but am still not too sure of what is what; my German isn't quite what it was.

At the moment I am trying to devise a suitable marking for an M41 say, circa 1963. However, as my collection of early Bundeswehr models grows I will need to identify others.

It follows that if there is any manufacturer out there producing these as decals (1:35) then any information would be more than welcome.

Any help would be much appreciated.

Thanks,

Brian
