Good Luck on your Heritage search. I have one Paul Bunyon. I have never handled a John Henry.
I have given up on even one of everything. I have too many with no boxes and sharpened and scratched. Two or three models I thought were over priced and I let them slip away, never to be seen again........
Anyone who is saving black Delrin scaled 300s, be sure to check for some white 'off-gassing' residue if you store them in the boxes for long periods of time. You can use toothpaste to clean it off and then oil or wax the scale to keep it black. I also use CLR. Other folks may have pet treatments. Back in the dark ages of this forum I did a post on this for FYI. 300
