I think your are thinking of the Case RussLock knife.
The 62009 is a Case 1/2 Barlow knife.
On the blade of the knife,if it reads Case xx over USA,,it's 65--69. Otherwise it's 40--64.
i had one and i got $150 for it it was a numbered kkk case xxx knife with red case
it means that they checked the knife and everything about it twice. So it should never have any mistakes. It turned into the logo for case knives today.
its around 20 and 30 i know cause i have a black and white diamond case
The case Chicago Bears two blade pen knife in case in mint condition with the red bone handles and 1972 date is 275.00
That is a Case Mini Trapper Knife. The CV stands for Chrome Vanadium. That is the non-stainless steel blade. Some prefer it to SS blades as it can be easier to sharpen.
do you mean numerical quantity or number of different patterns?
it is worth 50$
Condition is everything. The pattern is also important. You may have to consult an expert.
150-650.00
