WOW!
I'd 'wet myself' to dig any pre-1879 IH (esp any 1870's ).
I did get a 1864 C-nickel one 3 years ago , (just drying up from that one ) lol...It's in rough shape tho.
Ian, Nice Find! I know of another fellow that talks about the 1877 all the time and Want's one so bad so, as a little kind tease Kurt of Hoover Boys in your face ...................63bkpkr
Nokta FoRs Gold, a Gold Cube, 2 Keene Sluices and Lord only knows how many pans....not to mention a load of other gear my wife still doesn't know about!
