Tvr, Thanks for the photos of your nice Scout . The model 107 first came out in 1976, had a stainless guard and black micarta slabs and three smaller pins with a pouch style sheath . Many changes later came yours in the mid 1980's (1984 0r 85)with no guard, two larger pins and a different sheath and ebony handles . Your model most likey has 425M steel a great find and those models fetch a higher price on the bay . Hope this helps . DM
The model 107 in your pictures has black fibron handle slabs. These were offered starting with the 1984 Buck catalog but I have reason to believe a few were made in 1983. I do not have time to look it up. but I wrote a rather detailed article about this model for the BCCI newsletter about 5 or 6 years ago. It is archived on the club website. The black fibron was also referred to as impregnated birch and pakkawood and you can find it in different hues ranging to almost solid black to the one you have pictured with lots of lighter colored mixed in.
