I appreciate the advice, but I haven't needed to do such fine
measurement since I stopped rebuilding air cooled VW engines, some would
argue that it wasn't necessary even then, but some are idiots.
I'm really hoping that someone on the list just has this information
hidden away somewhere, because I just can't justify buying a measuring
device for a single purpose, and in this particular case Google is not
my friend.

A vernier caliper can achieve a measurement of the inside diameter accurate to
a tenth of a mm or better. It's an inexpensive measuring tool that I wouldn't
be without.

I don't remember if I ever posted this to the list, but I've been trying to
find a lens hood for this lens, since I acquired it many years ago.
When it was originally released sometime in the late 70's early 80's it was
shipped with a lens hood, and has a large diameter front filter ring, which is
unmarked, and why would it be? After all, those front filters were and are
extremely expensive, and it does take rear filters in a much less expensive
30.5 mm diameter of which I fortunately have the full set.
However the lens hood disappeared sometime before it came into my possession.
Given the cost of a decent lens hood in 95mm diameter or greater, (I've
measured the inside diameter and it might be 101mm), and the difficulty with
returning an inexpensive lens hood to China, I'm loath to order one that might
not fit.
The slip on plastic lens cover has an inside diameter of 106mm so 112mm the
next common size up from 101mm is out.
Unfortunately my tools and aren't very accurate for measuring the inside
diameter of the lens threads, (simply a metal rule in inches and metric), and
there's more than enough slop for the diameter to be anything between 95mm to
103, the later of which would be just a nightmare to find.
