Doug:
There was a time that Duke wanted us to attach our names to our work. Those of us that were capable* of running-in engines were each assigned a little rubber stamp and ink pad. I had mine up until about 20 or 30 years ago. (Used it to stamp my Kodachrome slides.) The stamped tag to which you refer should have my last name on it, too. The tag was placed upon the engine after it came off the test stand. I cant remember if it was a string w/tag, or was it just a tag with a hole punched to fit onto the prop stud? Been too many years. Anyway, I was supervising assembly at the time, so IF that tag is on an engine, then I was having to run engines to take up the slack for somebody that wasn't at their job post that day, OR, I was having to step in and make a hand in the run-in department in order get more engines out the door that day. Thanks God I didn't have to work the run-in department full time... it did enough damage to my hearing as it is.
* Believe it or not, being good at running-in engines wasn't a case where just "any idiot" could do it. The person had to have excellent mechanical aptitude, a thorough understanding of the function of the engines, and a good mechanical "feel" for them. A truly good one had to posses the aptitude to discern when there really was a production problem and bring it to my attention. (Items that my oft spot-checking of the final product would not typically catch.) A run-in man could make you or break you. I've had awful ones, and I've had (and worked alongside) excellent ones. Not just "anybody" could do it. One of the best was a fellow by the name of Chester Avis... and another that I can't remember his name. (I can still mentally see his face, though.) Those two sent out excellent engines. It was terrible when you had a dud run-in guy, and you didn't get to him fast enough before some engines were shipped that should have never seen the light of day. THOSE were the engines that eventually came back to my desk for repair.
I can't recall how long the "tag it or else" phase lasted at Fox.
Kenneth:
For some reason, the name "Sonny Perez" rings a very faint bell in the back of my memory files... but I can't truly confirm that I knew, or remember, such a fellow.
All fer now.
