no it's not a Trapper but an Office Knife? The knife is in "as found" condition.
I have seen some before on eBay months ago but not with this blade combo. Still has the factory edge and finish ( I think) plus great snap. I will let the Case experts have the final word on condition. I would like to know the age since the tested era is quite a span. Thanks!

It is an "Office Knife" pattern - 4257 or 42057 I cant recall which is the larger one, the spay blade was intended as an ink eraser blade.
If you keep up with Case knives, you will see many many of this exact knife with that advertising for Midland Chemical Lab - they made farm chemicals I believe and these knives were apparently giveaways for them. I have seen them all the way from Case Brothers through Tested through XX.
