Ted,
The R10 is choked .003 in the right barrel and .010 in the left barrel and weights 6lbs 4oz. The chokes and weight make it a great upland gun. The safety is on the left side. I purchased this gun from a gentlemen in Illinois who had an ad in Double Gun Journal about 4 years back. I paid as I recalled about half of what WLM wants for there R10. The gentleman still has a couple of rough 16 Darnes as far as I know. One that I remember was a halifax grade. One was a R10 that had the receiver blued that made me cautious. At least one had a straight English stock as I remember. He wanted to much for them and we never made a deal.
