I recently aquired a Bernette 715 and it looks very similar to the machine you pictured, although mine has fewer stitches. I would guess they are both in the 90s vintage. The manual for it was available at the Bernina website, although they are not made by the Bernina company, rather in Asia. Actually in researcing mine, I found a refernece that there is an identical Riccar model. Did you get the accessories? I didn't, but since it originally came with the generic snap-on variety, I just ordered a new set. I haven't cleaned it up yet, but when I do, I will test the sewing stregnth. I did run it a bit and the motor sounds strong. It will be one that I will re-home fairly soon.
