Elgin Grade 69, And Another Missing Pin

Here's an older Elgin, grade 69, 18 size, 15 jewels, made about 1871.

The oldest Elgin 18 size pocketwatches have just one case screw holding the movement in the case. 

Opposite this screw there is, or should be, a little brass pin in the edge of the movement that goes into a little hole in the inside edge of the case.  One advantage of this design is that the case can have two hole so that either an open face, or a hunter case movement can sit in the correct orientation.
A disadvantage is of course that this arrangement is not as secure as one would like.  And the pin is often missing, as it is on this example.

As a fix for this, rather than make a new pin, someone has replaced one of the barrel bridge screws with a longer one, and added a handmade brass washer large enough to go over the edge of the case.  But I'll replace the pin instead.
