I recieved an email shortly after ending my blitz today from a very nice man with some information that I really enjoyed....here it is

First the 43 Whittler

"Mr. Hughes is absolutely correct in that it being an older Case pattern. There is a more modern version of the "43" pattern which is an entirely different knife I know nothing about. The pattern Tony and Reese made is the old, original 43 pattern from around the turn of the century (second to last turn). It was made in the version you displayed in red bone as well as a version like it except in place of your clip point was the large wharncliff shown on the half whittler Reese made."

Below is another variation on this pattern
