It is the the Auto 5 Semi Automatic Browning shotgun. Named for the shape of the receiver that is unlike most any other brand of shotgun.

I would have to assume that you have a semi-auto shotgun.If your shotgun has a slight hump to the back of the reciever then it was a shotgun made with a browning patent and would have to be listed on the gun along with the royaltys paid to his patent.
What is your question?
The serial number you list does not match Browning convention. Go to http://www.browning.com/customerservice/dategun/detail.asp?id=13 to see what I mean.
A hump-back whale
The hump/bump(s) on the back of a camel is called protuberance. Meaning "stick out".
I must first say that sears did not keep any production records of the shotguns they bought from various makers.your sears model 102.25 was made by Stevens.The model of your shotgun is Stevens model 520A. These john browning designed semi auto shotguns had the hump back design noted on browning shotguns.these Stevens model closely resemble the savage model 720 with the same john browning design,and these were made from 1930-1949.
