Imperial Frontier 4815 U vs 4815 S

[DavidLea]

I have an Imperial Frontier lock back folding hunter with a number on the tang: 4815 U. I have a box for a Frontier 4815 S. What was this designation for? I can imagine that the S is for stainless steel, but haven't come up with anything for the U. I am thinking of selling the knife - it is part of a collection that my father-in-law had. It is great when we can find a box to match the knife, but this seems like a pretty big faux pas to put this knife in this box. May have sold the one that belonged in the box when I was still trying to figure this big collection out!

Would appreciate some seasoned advice!

If you can post a picture of the knife esp with blades open, a couple views and pics of the box. That would help as it is very hard to remember all the knife patterns by number. Most of us have 2 or 3 brands we collect and it is near impossible to remember one brand and model numbers, let alone a third or fourth brand.

I don't think most of us are familiar enough with Frontier patterns to know them by number.

Larry may have the information, but I seem to recall a Frontier 5" lockback with a drop point blade, but I don't see it on the list just Larry posted.
Anyone remember the model number of the drop point?
