Fitting the Finder & Flash
To get the finder to fit to the 110A, spots need to be ground and numerous holes must be drilled.
Tape the plate and housing together. Place them onto the camera, mark and cut. Rough edges will be fixed later.
If you place the mirror box onto the camera body, you will notice that when you push the springed lever, the mask gets stuck on a lip. Grind this lip flush.
Place the plate onto the camera. Notice that only one hole lines up with the body, red arrow. To secure the plate, drill two new holes, green arrows, the second hole is because I will not be using the flash screw, purple arrow.
Because of the missing side of the camera and that I am not using the flash screw, the plastic housing only has one point of contact to hold it secure.
Originally the front screw access hole was slightly to the right. Drill an access hole where this notch is, blue arrow above.
You may have noticed that the 900 lacks the wrist strap part found on the 110A finder plate. To remedy this, hack the piece from the original plate. It will be held in place by the screw that already goes here.
Now you will definitely notice that the plastic housing lacks a place for this piece to come out. To make it easier I flattened the piece with a hammer.
I cut my notch and lightly sanded it round. I also check with the leather strap for enough clearance. In the end, you can bend the piece up or down depending.
