Yes, only the right handle moves on all Fisher double door stoves. older doors have a groove cast into the back of the left door to hold the bend in handle from moving. There is only one wedge inside on the top edge that pulls it in tight. Close the left door first and the right overlaps. Yours should have a momentary pause as you have to rotate one way, open slightly to give it a gulp of air, while this pause gets it drafting, then rotate back in the other direction to open fully. This is a lag in opening door that prevents smoke from rolling in. It may seem cumbersome at first, but you soon get used to it. One of the guys in Bob's shop came up with that idea and since Bob was familiar with the patent office, had him patent his own invention. His patent motion is used on truck and trailer gates as well as other items. That is why only one door has a latch. I don't think Bob had to pay him royalties using it, at least I hope not!
Every picture I have of the inside of a left Grandma door has the optional nickel heat shield.
Here is one thread bricking a Grandma III;

The drawing picture is for the old style with angle iron corners. It won't help you if you have the bent corners.
If yours has angle iron down the corners that become the legs, the brick layout is not in the early manual. I have it from the drawings. The fabricators were sent revisions of drawings, and the 1977 revision is called FS II. This was the early box with bottom and rear shields added, optional if not installed on a hearth. There were only flat top double doors from '76 to '78. In1979, the arched top doors were available as an option on the old box. These were designated III, and UL approved. In 1980, the flat top doors were dropped, and the corners were bent with no angle iron on the corners. They remained the III. New style glass doors became the IV. What makes it confusing, is many fabricators offered the old style box as a cheaper alternative to the new bent units. Yours probably came from the Dunn Brothers that had the license for VA and W VA. Not sure what they did.
This numbering system is ONLY for the double door stoves.
Can't find the drawing picture on the forum, Maybe I only posted the Grandpa double door. Each part has it's own drawing and the size of prints are far too large for copying, so I can only do it with pictures.

If you run your bottoms across in 4 rows, you think you only need to cut 4. Stagger the full length and cut off back and forth. They cut very easily with a masonry blade in a circular saw. Score and snap like Cement board. Much softer than regular brick.
All manuals are at the top of the main Fisher Forum page. In the sticky thread section.
More pictures of brick layout from drawings are in threads titled Mama Bear Firebricks, or Papa or Baby........ Firebricks
