The stamping was on Ruger rifles made in 1976. If you find the right buyer, he might pay a bit of a premium for a rifle with the logo, but for the most part it doesn't add a lot to their value in today's market.

In the era that the Liberty rifles were built, Ruger was the target of a lot of criticism for the alleged poor quality barrels they were using. Supposedly they paid $3 per barrel for outsourced barrels. Some shot and some didn't. Ruger Roulette.
The issue improved once Ruger started making their own barrels in the late 1980's with full production for all rifles taking place in the early 1990's. 1989-1991 was a phase in/phase out time for using up old outsourced barrels and moving to using new ones made in house
Supposedly this is the barrel history for Ruger 77 rifles. I have no idea if it is correct or not, but it's the standard history quoted by Ruger experts.
Douglas barrels 1967 - 1973
Wilson barrels 1973 - 1991
Ruger barrels 1991 - Present
