Sorry to be so late to the party. I have a 16ga, Westernfield Deluxe. Mine is an Ithaca, Western Arms, Long Range Gun. It has nice checkering and ejectors.
Western Arms serial numbers range 1-65xxx. They have a dog engraved on each side of the frame. The trip is located below the barrel extension.
Nitro-Special serial numbers start at 100,000 and run to 302xxx. There will be a goose in flight on each side of the frame. The left side of the top lever has a bulls eye vs being checkered. The trip is located forward of the breech face, similar to the NID.
