The original file is simply visited/opened using C-x C-r. The
background for the question is that I often find myself thinking "I
did something like X in projectY", so I open projectY's masterfile
using C-x C-r and then find the code snip I need using either a
regexp-search or the ToC buffer. I prefer readonly to make sure that I
don't accidentally make changes to projectY. (Of course, I could call
M-x toggle-read-only on each new buffer, but I think it would make
sense that thay are automatically read-only if the "original" is).

I can see that find-file-noselect unfortunately does not have an
option to set the read-only status of new buffers, so it is probably
not just a question of passing the current value of
buffer-read-only. I don't know if there is a simple solution, nor if I
am the only one who would find this useful.
