What is wrong with this picture(s)?

[jetlagdave]

I am new to Lugers and the forum and would appreciate any help from those of you with far more knowledge than myself with the following subject.
I wrote a previous thread concerning this Commercial Luger but now I have more information to hopefully generate an answer to the question as to why it is void of ANY proof mark.
It is a 3 line Stoeger American Eagle.
Serial # 405 V.
Trigger.."05"
Take down lever "05"
Take down plate "05"
No ser #s on any other small parts
Extractor..."loaded"
Safety........"SAFE"
Magazine..."GERMANY" in wood base
Right side frame....see photos
Grips.........no numbers
Front of receiver: 405V, "GERMANY", flowing V
6 inch barrel, no serial number or proofs

My main concern is the absence of proofs and a rear toggle (DWM) that appears to have a phosphate finish. And grips without numbers or "Germany" on the underside. I am considering purchasing this gun and I suspect the value would be drastically reduced for the same model WITH proof marks. (Fake?) I also feel that the American Eagle should exhibit a greater degree of "crispness" for a gun that looks so nice in other respects.
Didn't mean to get so "windy", but I think my other post lacked sufficient information for educated answers.
