Large c1930s? hand coloured photo of Lake Fergus mid century retro not Whites

Large (716 x 576mm) and beautiful early hand coloured photo of Lake Fergus (Eglinton valley)NZ. Very good condition with great colour behind its original glass. According to the details of the only other photo from this series that I’ve found, it is described as a "circa 1930 Albumen print" (see pics for the smaller B&W version). Unknown Photographer, maybe someone recognizes the hand writing? This is a large print for this era, I have carefully removed from the frame and cleaned both sides of the glass and re-tapped the back with the correct paper tape to keep the bugs out. added a side by side (pic 8) you can clearly see that they are the same photo or from the same series, although the B&W extends further to right. If you look at the top left corner and the top right edge of the tree it looks as though there has been a very slight angle change. What appears to be buildings at the far end of the lake in the hand coloured version (pic1) are just reflections in the glass. Dimensions; frame size, 716w x 576h mm
