Camillus was making knives for Moore Maker of Matador Texas from the early 1990's. I am not familiar with the history of Kabar other than they stopped making folding knives about 50 ? years ago. Camillus made many (or all) of the Kabar branded folding knives since then. More than 50% of the Camillus output was contract work, i.e. knives that have some other company's name on them.
Up until Camillus closed in 2007, they made all of the knives with synthetic handles for Moore Maker and Queen made the M.M. knives with stag or horn handles. Hence my see through lock back could have been made by Queen or Camillus. As Camillus was also making Kabar knives it seems likely that Camillus made both of these see through lock backs.
However as with much of knife history, a logical assumption is not always correct.
