Truth is, I really don't care that my 1975 6207 is Delrin...yeah, I may have overpaid for it (nothing new about that), but the main reason I got it is because I needed it to fill an empty slot in my 1970s decade Mini Trapper collection...and it does that just fine, regardless of the handle material.
And, honestly, if not for the shield, I don't think I could even tell it was Delrin and not bone.
Case in point (no pun intended), this is my latest addition: a 1977 Brown Bone 6207:
