sunnen is located in st.louis. i actually worked with sunnen in the late 70s in developing fixtures holding and honing various harley components ie cylinders, cases, etc.....
that's cool...we had a Harley barrel fixture for our CK-10....held two barrels side by side..couple of 1/2" aluminum plates with a center hold down stud...I don't remember if it was factory Sunnen or something we made in house..this would have been around 78-'79
there was a Sunnen factory rep named Frank Steenstra (sp?)...little old school guy who smoked a pipe. You could call him up if you had a problem or needed instruction on a new piece of eqipment. He would show up with a suit and tie on, get a cup of coffee, light up his pipe, roll up his shirt sleeves and start operating the equipment. That guy was a genius with that stuff, I loved learning from him....man that brings back good memories.
I miss the 70's...gotta see if I can dig up some old shop photos.
