Joe, I believe I read somewhere that the Kenmore 84 is a Pfaff made machine. I do know it's marked "Made in Japan", so that may not be accurate, I don't know that Pfaff had a Japanese factory in 57.
And yes...I have cams for it...3 sets! LOL!
One of the reasons I love these oldies....the whole setup for mine cost me $37.00....$15 for the machine in it's old cabinet, $20 for the desk cabinet, and $2 for the one set of cams....
I really like that base on yours.
