I don't know who made Indestro's, but most of the wrench makers outsourced the torque wrenches , only a few companies actually made them, TCI, Sturdevant, a few I forget. That is good, because the recalibration folks actully only deal with a small number of actual types.
Ususally the TCI ones say TCI under the torque handle if you unscrew it far enough, but not always....
Calibration is fairly pricey, and it could be uncalibratable if someone abused it....
One place I picked at random lists the Indestro 8081A and Indestro Super 8089 as being calibratable...
Expect prices ~30-$150 , with a tracable certificate, plus shipping both ways...
PS: Most places still charge you if it can't be calibrated...
