5100 Stevens Side By Side Shotgun?

I purchased a Stevens side by side 20 Gage shotgun but wonder what model it actually is.

I searched the net and found many similar shotguns with a dog on the receiver and identified as a model 5100, mine has a goose on the receiver.

Is there any significance to the goose and is it in fact a model 5100?


Any help would be great, also I need a buttplate and screws, if you have a set available for sale please let me know.

Wondering if the Stevens 311 plates will fit, the 5100, 311 and 530's were all built on the same action, can't see why they'd change out the stocks very much.
