Ken Georgi would have the answer to your question, I think.
Eight,
Thanks for the suggestion...I have been meaning to drop Ken a line. I just wanted to try gather as much general information here as possible before asking him about any specifics.
Earlier you also mentioned that your gun had folding rear sight but no peep...I am not sure if you could tell from my pictures but mine has both a folding site and a peep. In other words mine is exactly like yours but has one added feature.
I believe small features such as the peep is what distinguished the grades within specific models. While mine certainly does not seem to be much above a field grade, based on the presence of the peep, I am sure it was not the lowest grade.
Based on what I have seen it seems the presence of a "trap" on these guns is what marks the next level above our guns in terms of hardware.....
