Lureman,
If memory serves, the orginals are numbered on the reverse of the handle below the clip tip. The knives that were made for the Evolution set are numbered on the front obverse bolster. I've never directly compared the two, but the original handle slabs are very thin stock compared to even other early models with unbeveled edges. The clip (two screw)is not bent at the tip. Also the opening hole on the first model seems to be smaller. Sal would be the final authority on these points (please correct me if I'm wrong!)
