Captain, as the rest have mentioned this is a very nice 1123. I sold my Remington/Case collection several years ago and in the collection was a 1123 that I decided to keep. Yours is in very nice condition and as you probably already know the old ones had exceptional edge holding abilities. I use my 1123 and it never touches anything other than a kitchen steel and a strop.
Getting to why I really posted is your sheath! After I decided to keep my 1123 I started looking for something to carry it in and found one exactly like yours, it wasn't cheap!!!! I ended up with a custom made sheath instead. You might want to do some research on the sheath because the one I was looking at was from a Remington collection also. Great buy and a great knife and sheath combo!! Take care and God bless. r.cordell P.S. I am now addicted to Randall's .....God help me!!!!
