Oak Puritan Baroque

[phono-phan]

I was able to bring this home yesterday.  I have  had one of these models before but this one has all the metal parts nickel plated.  I also can't figure out the little drop arm on the tone arm and the bracket below it on the motor board.  It has been refinished and they saved the decal.  The overall condition is pretty good.  Does anyone know what the drop arm is on the tone arm?  Also, does anyone have any documentation of this model coming with nickel plated parts?
