Greeting Lonesomebob,
I have a Harold Robbins percussion lock made in 1971. It is one of only five he made after receiving an inquiry from me.
It is not for sale, being on my favorite ML hunting rifle and will be left to one of my grandchildren with a complete written history of the rifle.
Best regards and good shooting,
John L. Hinnant
