Bitsavers has some manuals for 1630 and 1650. Maybe those will give you enough info to be
useful?

Yeah I saw that, but I'm a bit reluctant to blindly pay USD 50 for something that
might not even have any detail on what I'm looking for. After all, I don't need a
full manual, and certainly not a collector-worthy copy. I just need this specific
information.
