Mike Reese Carbine

[Mike B]

Merry Christmas all,
Many years ago, I had the pleasure of being invited to the home of Mike Reese. At the time he was working on his study of the American Eagle test Lugers. He had Lugers, books, documents etc. spread all over his living room floor. It was a very memorable visit.
Yesterday I picked up his book, "Luger Tips". I had not looked at the book in quite a while. Something caught my eye. Take a look at the carbine. Is this correct? A carbine sight and a rear toggle sight? Seems like the rear sight would have been eliminated on carbines. Any opinions?
