The "77" on the side plate looks a little odd, but could be the picture, or the stamping itself. I do not have a 7 on mine to compare to either. As far as upside down on take down, mine is the same as yours. Grip safety apears buffed, look at upper corner. Also, 77 seems a bit larger than it should be. I would like to see a 1900 posted with a 7 in the # to compare.
Someone with more knowledge than me on early commercials will chime in I hope. John
