Hi Larry
Thanks for the reply. Thought maybe my question had caused the list to 
crash as yours is the only message I have seen all day.
I never knew David Bradley made a hammer mill. Most of the major machine 
companies made them up here and they were all much the same design. This 
IH is only a ten inch compared to the 14 inch Case I have been using 
forever. Same general design as yours, flip up hood to change screens. 
Funny thing about those screen hole diameters, we always used the small 
hole screen (maybe half inch) for oats chop and then changed to the big 
(about two inch) hole screen for straw and hay. The small hole screen 
wore so thin that I quit using it and just left the large hole screen in 
for grain. Surprisingly it still makes chop just as good as the small 
hole screen did, and probably at increased capacity.
The major difference this IH has from the Case is the style of hammer. 
The Case had solid, four sided hammers arranged on "spokes", about six 
rows if I recall right. The IH has swinging hammers, much like a combine 
straw chopper.
I checked my machinery brochures from way back and Case was only 
offering a p.t.o. hammer mill by 1961. Guess belt drives were becoming 
obsolete by then. IH did not even show a hammer mill in their catalogue 
by 1963.
