I think vintage TR racers pre-bed-in the plastic cam foot to the cam by
slipping in a piece of fine emery paper in between the foot and cam and taking 
a
few strokes off the plastic foot to get a more accurate fit to the cam. Normall
y
ignition points rapidly bed-in on their own within the first couple hundred
miles (and your gap gets smaller just as fast). I guess racers don't want their
new points gaps changing during the race!
ps; Don't all 4 cyl engines use similar dwell? The Volvo 122S book says 59-65
degrees @ 500rpm

'63 TR4 since '74

If you make it a habit to smear just a tiny bit of grease on the cam at
every oil change, the "thingy" won't wear as quickly.  Put a drop of oil
under the rotor while you're in there.
