I own both the Williams and a C series Sheridan. The instructions that come with the sight show it being mounted on the right side of the "Bolt receiver" Unfortunately My Mounting plate & holes is on the left side of the "Bolt Receiver", meaning if I tried it the sight would be backwards. So I looked at the photos in the Bluebook of Airguns and there is a photo of a Benjamin model 397, S397 & 397C with a Williams sight mounted on the right side. All the photos of the Sheridan's have the mounting plate on the Left side. So I would say "No."

The "P" designates peep rear sight & ramp front sight, not sure of the "G" designation.
Should be a Stevens rifle, but the peep sight would probably be aftermarket. If you can send a digital picture of the rifle and a closeup of the sight we can probably ID it for you. sales@countrygunsmith.net
Most came with a tooth ramped iron sight.But there could be different styles depending on the age of your Winchester model 1894 rifle,such as a peep sight,a full buckhorn sight,etc.
