leonf is right of course, that is a White slide plate. What it means in some sort of realistic terms is that the machine is post 1924 when White acquired Domestic. (Domestic had been making the Franklin for Sears, so White became the supplier.) And... it appears to be a White FR which was made into the 30's. So that sort-of dates it. =) You -should- be able to thread it from a threading diagram for a White FR.
Nicely done. Really. Great looking machine. I hope you get it sewing soon. One of the best for hems.
