torque wrench

That Quinn is 20-100 ft-lb. Drain bolt is something like 27, so you will be at the low end of the range. Not ideal. That wrench would be good for lug nuts, though.
Torque wrench accuracy is rated as a percentage of the setting. So, 27 is as good as any other place between 20 and 100.

Before I retire, I was a calibration technician. The old sears wrench was entirely different.

I have an old Sears 94443 in the garage, that has never been tested, and has a chipped tooth in the drive gear.

Is there still a possibility that it could be serviced, or just something to keep around for nostalgia at this point?

When working in manufacturing engineering, and needing to torque a fastener, to 27 ft-lb, for example, I would never get the technician a torque wrench with a range of 20-100. I'd be looking for a 10-50 wrench, or something close. Not to mention, a 3/8" drive wrench, going to 100 ft-lbs, is not an ideal application either.

All the same accuracy, as long as you stay between 20% and 100% of range.

20% of 20 is 24 lb.ft so the 20-100 would be no problem whatsoever. Ansi spec on a 3/8 anvil is 150 lb.ft so what is the not ideal?

Well, maybe I'm being a little on the "ideal" side. Just saying what I'd do. Torque number should ideally be in the middle of the wrench's range. Just me, again, but if torquing something to 100 ft-lbs, I'm grabbing my 1/2" wrench.
