All About Pocket Knives

Good day. I'm hoping someone might be able to help me identify a Case pocket knife I have in my possession. Markings show the model as 53131P and Case Bros. Springville. I inherited this knife from my father several years ago. He received it from his father prior to 1955, when my grandfather passed.

I've included some photos of the knife, though the blade markings did not show up very well.

Any assistance or advice on this knife would be greatly appreciated. Thanks for your time.

Beautiful Old Knife, look like a Case Bros. Springville , a very rare knife. It was your Grandfather 's so that makes it priceless. Thank you for showing us.

Wow that is one rare bird. Hard to put a price on a knife that rare but I am sure there is many a collector that would love to dig down deep in their pockets for that one. Springville stamp dates it c. 1912 - 1915.
