[SEL] Foos Model J Mixer

[Michael Tucker]

Howdy all,

I'm trying to help a guy that contacted Rob about a Foos engine. 
Does anyone have a picture of the mixer on a 1920'ish 3-1/2 hp Foos 
J?  From the picture that he sent to me it has what I'm bettin' is 
the mixer, although it's quite different than the mixer on my 1910 
Foos Jr.  So, a good picture of a later model J mixer would help me 
clear this up.

The original mixer on my Foos Jr. was made out of brass.  Is the 
mixer on a later model J made out of cast iron?

Thanks,
Mike
