That's pretty close, but...
I think the only inaccuracy is about S/N's 19 & 20 being the 'only' green handled versions. I believe your picture does show S/N #10 as being green handled, and I've heard there was at least one more....other than that you're pretty much on the mark.
The fellow that has #19 also had #20...he tells me that they were both green...we're trying to buy #19 from him now.
We have #17, and it's black handled. My 'color-glossy' copy of the J.C. Devine catalog from the Applegate Estate sale clearly shows, and identifies, S/N's 00001, 02, & 03 as black handled versions.
When I talked with Bill Harsey at the Eugene knife show a few weeks back, Bill told me that the Col. supplied the non-black handles to BJK, and he thought it was around a half dozen sets...
(Bill had all the white and green handle sets, so he should know, but didn't want to talk about BJK, period.)
It's a real shame that that 't*rd in the punch bowl' Ted Wood has/had S/N 00000 in white...there just 'ain't no justice' I tell you...
Hope that helps.
Great site Tom, kudo's!
