Hey Bob..!
Sorry about the delayed reply - seems that you were posting while I was sleeping <img border="0" title="" alt="[Wink]" src="wink.gif" />
Remember, the parts guns were comprised of spares at the factory, and among those "spares" were parts that were "rejected" for numerous reasons. I caught the mal-formed toggle ears when I first saw the pictures - and frankly - it's one of the several reasons that initially lead me to believe it's correct. As for the takedown and pin - yep - great eye! Both the pin and the lever itself are suspect, so I requested close-ups of both.. There is something about the checkered pad on the lever that caught me the wrong way - but, it's only shown in one photo, so it's tough to tell.??? Same with the trigger toe..?
As for Oscar and P.A.T. being in line with 'ole Hargus.... Sheeessshhh - I wish these Lugers could talk..!!
Best to you!
John
