I have no idea what the experts think, but I share your curiousity. I'm not sure why the seller says the slide is a replacement unless he did the replacing. According to Sutherland and Wilson, the serial number falls within the correct range for a Remington Rand pistol, so the slide is correct--as you said, they aren't serial numbered. The pistol is rebuilt, like 99% of M1911A1s, and the condition is a bit doggy. Still, I sense that USGI .45s currently _start_ at four figures. Maybe it's the economy, maybe its Xmas competing for discretionary income.
