I've done a bit more research using the Squadron book. It appears some models used a separate inner gear door. Which means the outer gear door did not have the small appendage on the very bottom. But, as to which models were like this and which were not, I cannot make any definite statement. But, at any rate, unless you split the lower half of the door and tied it to the moving strut (somewhat like the Zero), you will likely have some problems on landing, with the door like it came from Top RC.
