Questions for someone owning an original complete 8094 Control Center

I have an incomplete 8094 Control Center, and a few things on the parts list lack information. For instance, there were originally paper sheets included. But I cant seem to find the exact dimensions. Another thing I dont have is the pen. And I would like to have some detailed photos and length/thickness measurements.

These things are not available anymore. So I'm looking for close replacements. The paper I can just cut to size from bigger sheets. The pen is just a pen. But I'd like the replacement to be as close as possible for the looks.

So if anyone can help me out that would be great.
