You could be right. I've kept records on over 150 Reilly shotguns though, and most are in the 6 lb range. My own 12 ga hammer gun with 30" Damascus barrels is 6 lbs 2 oz. This gun is a pound and a half heavier. Reilly was known for pigeon competitions in the 1880's. Anyway, we'll see what the dealer says.
Here's a real deal Reilly Pigeon gun - 8 lb+ weight - 3" chambers; choked - with game rib (makes me wonder if the above stock is a replacement):

On the gun for sale, the very haphazard engraving of the Reilly name and address on the rib is oddly out of character for the company.
