Thanks to both of you for verifying that $1100 is too much. The pictures posted are too small to see much detail. I do think it's a DWM as the receiver doesn't appear to be notched for the Artillery sight. But, there may be an Erfurt proof mark on the side plate. But, as I said, detail is hard to see. A link to the listing is below:
