Pete did the blade etching. Pete also did the early blade etchings for Tom's Vietnam Veteran Model #14. Pete had SF logos and various other logos he would acid etch. The cursive signature was one of Pete's favorite "projects".
Hope this helps, Capt. Chris
PS: It should be noted that Pete also did some of these etchings "while" still active and "at" the shop. I have a couple that are 100% legit! CCS
