Nice TL-29 LT!!!

They are all nice, but I especially like the the TL.
I really like the shield on yours. It dresses up the knife nicely.
It just so happens I have a thing for old TL-29's. Having carried a Camillus all through my time in the Marine Corps, including overseas, I really appreciate the quality & durability of these old girls.
My wife totally surprised me this Christmas. She had asked me what knife I wanted and I told her I was currently collecting TL-29"S (and explained what they were) and I also had my eye on a split back Ulster whittler. I was watching the Ulster & knew she won it so I was quite pleased. Imagine my surprise on Christmas morning when I opened a package with three TL-29's in it. The first was a nice wood handled no-name. The second was a great wood handled Kingston, and the third was this Schrade Cut Co. I was really excited!!

She asked, "Did I do good?" I said, "You did outstanding!"
Not to hijack the thread, but that is how I got my Cut Co TL-29.
Question LT;
"Which is the older one, yours with the shield or mine with the TL-29 stamped/engraved in the wood (along with some bozo's initials)? Or can they be dated by that criterion?
