Mine's a Model 1 - with a 6" stainless blade, nickel-silver hilt and a black linen micarta handle, in a 'Johnson Roughback' scabbard - though when I got it, there was no such designation - it was just a sheath with a stone.
It has my name and serial number etched on the blade.
My first tour, I carried a Model 15 'Airman' that I sold to my Medic to finance it - we both still have them - and it's been everywhere they can send a soldier that's difficult to spell - on a couple of occasions, more than once - and it's done so for several decades - and still looks good doing it...
Back then, an APO address made a world of difference in getting one out of Orlando and into a soldier's hands - I only waited a couple of months.
In SEA, a 'lot' of custom knives were carried - Randalls, Ruanas, Morseths, Coopers, etc. - all the professionals had them, and wore Rolexes and Omegas, too.
Today, it's Casios and modern-styled Ka-Bars.
Times changed...
There's another thread on Randalls here, somewhere - with a lot of good photos.
