Welcome to the world of Japanese clones!! They come in all kinds of awesome colors and turquoise is one of my favorites!!! Are you thinking of buying the one that you posted or did you already buy it?
My first vintage/machines were the black Singers and then the tan Singers. Now I drool over all of the beautiful Japanese clones that I see and I have collected a 'few', too....
There is a Yahoo Group dedicated to these machines in case you are interested. They have lots of helpful info in their files that may help you to find out more about your particular machine. Here is the link:
