That is a badged machine, meaning this certain company made machines and put whomever's name on it that wanted to sell them.
I need you to get me the JA or JC numbers that are on the machine and post them. These should be cast on the bottom and you might have another set stamped on the side of the machine by the plate with the model number.
I am currently doing research on the Japanese machines (The model 15's to be exact) on how to date them and to see who and where they were manufactured. The JA and JC numbers help me alot in finding out the original manufacturer but it is up in the air about dating them.
But if I was to guess your machine would be in the mid 60's to the early to mid 70's.
