Keenserts Master Thread Repair Kit

Description

Well over 30 years old. This set belonged to my girlfriend's late father that owned an Automotive repair shop. Not sure about what all comes with it, I just know that she was told it was worth ,000. She is clearing out the warehouse and will sell it for 0.
Each box has one or more pieces in it and there are a number of other extra pieces not in boxes (see pics). Many of the boxes are labeled "insertion tool" and seem to be different sizes.  Comes with original metal case. Shipping is flat rate for domestic.
