All About Pocket Knives

Recently I just bought a hand full of vintage knives at a auction, and I have one that I can not find any info on the pattern number. It is a W.R.CASE & SONS, BRADFORD,PA. pattern number either c or 6 2016S, we are not sure if the first letter is a C or a 6. It looks like a 2 bladed jack knife, and its a nice old knife. Any info would greatly be appreciated.
Im starting to get the collectors fever, and I have been collecting, But I just dont have the knowledge for it yet. Apprecite all the help anyone can give. Thank You!!!

Hi Majorhunter and

Might there be a chance you could get a picture to post? I'd say it would be a good bet to say the first digit is a 6.
What is the closed length? ...3 3/8"?

Thanks for the reply so fast. The knife measures 3 3/8, and I hope the photo helps also.

An unusual and nice looking old Case knife.

Pattern number is likely to be 62016S

6...means jigged bone handles

2...means 2 blades

0....means a pattern modification, in this case the addition of the lower bolster

16....is the pattern number for that frame style, a 3-3/8" regular jack

and the "S"....means "Sheepfoot" master blade

Thank you for the response.
