No gears could be seen throught the filth ...
... BUT !!! IT WORKED !!!



R E M A R K S :
The CAPS on the DELETE-LEVERS were MISSING and had to be home-made ...

            

        ... out of 3 layers plastic - glued together ...

            

        ... shaped with file and sand paper ...

            

        ... and finished with black shoe shine.
