All About Pocket Knives

ok im new to old style pocket knives, and trying to aquire a camillus stockman in carbon steel. not finding definative info on what to look for. when buying from ebay, i cant hold the knife in hand so i have to reply on photos.

is it safe to say just look for blades without "stainless" stamped on, and are not their latest stamp like example below?

im trying to find a model 66, 67 or similar. large stockman with 1095 carbon steel (clip, spey & sheepsfoot). thanks

Personally, I look for rust. But for a user, I place preferred steel over cosmetics.

The absence of a "stainless" stamp does not mean that it is carbon steel.
Model #66 produced before the end of the 70's and had a carbon steel.
Model #67 in the early 90's received stainless steel.
In the picture shows a tang stamp from 1989 to the close.
