By accident I was able to get a orignal Marzocchi Tool-Lit Case (XC500 / XC51) from 1994 with most of it’s tools included. Marzocchi article number is 60.10. I bought it because I always like to see the original tools Marzocchi has build in the past. 
The original pump was missing, but thats no problem as I have a box full of it 😉 

There was an original Instruction Manual for XC500/XC51 included, which I haven’t seen before.  

Will add some pictures later. 

Here is a gallery I created about Marzochi Tools:
