Gar,
All original engines have a VIN stamp, no exceptions. Glad that you able to determine that yours is good.
I have no idea why your timing gears went so quickly but don't believe that it's a common problem with steel gears. It's known that the nylon gears from the 80's were cr*p.

The question now is why did the timing gears go this early and try to destroy the motor. I did the gears myself 2 years ago next month. 2 years and 2000 miles later I have junk in my oil which turns out to be rod bearings. They installed a new crank and all new bearings. I also want to give heads up for all of you. These dual gears are fine teath and seem to wear soon. Now I have 54000 miles on the car and wonder when to replace the gers again?

It not at all difficult to install the lower gear improperly, the lower gear usually has a recess for the fillet on the end of the crank and it becomes difficult to see if the gear is fully seated. Depending on if the proper tool was used to install it, or if the lower gear was installed with a mallet.
If you have a new dual roller installed I wouldnt hesitate to let it go for essentially the life of the car, depending on how many miles a year you log. For me right now it would likely take 20 years for me to get to 100k miles
