Here's the area I was trying to describe:
Location:I've only ever seen a couple of Lithgows. The last one a guy tried to sell to me, claiming it was a Springfield Garand he'd bought at the CMP. He wanted $1,000.
Fortunately he didn't live very far away from me so I went over to look at it. Saw immediately it was SAI. He refined his story to say he was at a match at the CMP
and bought the rifle at the SAI booth. Lithgow receiver. I passed. Opinions on the CMP forums was that the rifle was worth about $400- the sum total of its USGI parts.
