SBT - What are you thoughts..

[David]

You all have provided me more information in 2 hours than i have known for 50 years. I appreciate the feedback. Here are a couple of additional photos. I wonder about the engraving... maybe solved when I get information from the build sheet -- original owner maybe ? was this done at the time of build or added later ? The gun is not without blemishes .. I am sure it was used at some point and likely tossed in the back of a truck and hauled out to the field. everything was a tool back then .. no special cabinets or safes etc.. shotguns were leaned up behind the back door ready to go to the field.
