Given that it was well used, could well have been just
overall wear.  You set the low gear limit back when it was
less worn, but now all the pins and pivots are sloppy. Only
takes a couple of millimeters more travel to go from normal
clearance to engaged on a spoke.

Thanks for that expert opinion. Makes me feel good about having
changed out my old derailleur at just under 35,800 miles.

 
Thar's 57000 kilometers. Don't think many people have ridden
that far in their lives....
Mine had quite definite signs of wear, though nothing was
loose.

Any other well worn bicycles nearby?
Hold the bottom pulley in your fingers and move it
laterally. Note there's play at the pivot between cage and
body and also all four body pivots besides the top spring
pivot. That will be minimal on new units but excessive on
well used derailleurs.

My son's Monark has a Shimano RD. That's quite stiff to move
as you described. It's at least 20 years old and has been sitting in a
corner for ages so it might be just dust and rust. Dates are complete
guesses ...
My right arm is not working. I had a compete rupture of my
supraspinal tendon when I fell last year. I went to an orthopedic
surgeon, but he said "I wasn't worth operating on" because of my age.
"It'll be at least 30 months of physiotherapy and you might not last
that long".
The joys of aging.
I'll ask my maid to carry the bike onto my stand so I can
check it tomorrow. Can't lift it myself.
My only other bike is the 1976 Caloi, and that does not have
variable gears.
