An Unusual MR-73
We recently took an MR-73, and ended up finding this.
Not the usual emergency brakes design
On element 22
Once again
On 78-022, all of the signs are made of a different material for some reasons. And again, all the emergency brakes cases are all different from the usual one. From this photo, it might look like just the normal one you're used to seeing in these MR-73 cars, but this one has a larger and wider shape. My guess is that it was a prototype before they renovated the MR-73s in the 2000s.
