Serial Numbers Application Updated

I did a quick bounce of the Elgin watch production data application today, to fix a couple small problems, and also to all links to a model reference on earlier Elgins.  The model reference allows models to be correlated with grades.  This only allies to earlier watches because Elgin stopped publishing model and class information in 1915.
