That usually was printed on a decal/label on the box they were packaged in.
This isn't my tool. I've never had a set. That is from Pantera Place.
My experience with these tools with other kits from other cars is they are pretty self explanatory and you will figure it out very quickly.
I don't know it you will get all of these pieces in that kit number listed above.
Even when you find an original set for sale you need to verify that the set is complete. Few sellers know anything specifically about the tools and tend to be just in the business of reselling them.
I'll bet you a nickel that the seller will want a lot for the kit just because it is marked Pantera.
Most of the kits I'l purchased sell between $100 and $150 for the set and most were never used.
