I am grateful to all for your contributions. It has truly been educational. So it looks to be a referbished yet seemingly all SC 03A3 however I missed checking the extractor and buttplate.
As of this minute I still haven't heard a word since I made my offer on Thursday. With it now being Sunday and after increasing my offer after reading the responses here there's still no word. So par for the course in the anals of my trying to aquire an 03A3 as there's always something new added to that multitude of reasons.
In short I've put this one behind me as I have the hundreds of others previously attempted and I look forward to finding the next.
I thank you all for your educated input and hopefully I may tap this great base of knowledge yet again when the next one is found.
