Im familiar with the Knight KP1. The 45/70 makes a fairly good 45cal fast twist ML conversion too.
The H&R reference was sarcasm because it was one of the first if not the first modern inline offered. Knights did not come out until about 1985 so the H&R would take the "traditional" production inline trophy.
There were a one or two others made around 1969-1970 in very limited numbers.
