Viking Designer
 

I have this green Viking Designer. tagged National Sewing Machine model 70. it is stamped ZZ 18591 on it.
I can't seem to find any information on it any where.

That is an unusual machine. National made a lot of machines that are badged with different names. You might try to join National Sewing Machine Company group at https://groups.io/g/NSMCO I wonder, now, if perhaps it was not actually made by National. It looks like the same machine as seen at https://tightacres.blogspot.com/2016...ti-zz2000.html which says "by a distributor for National Sewing Machine Co."

There is also a Borletti Group, but you have to join the main Group first. The main group is https://necchisewingmachineclub.groups.io/g/main and then the sub-group is https://necchisewingmachineclub.grou...lettiVigorelli

Good luck.

Wow! Thanks a lot. That is great. Now I can try to find a manual for it. The machine does say on it Reg.U.S.Pat.Off.
made in Italy.
The motor is a Westinghouse.

Good luck. I hope you can find a manual. It looks like a good machine. If you do find a manual, would you please get back to us for future reference? Please.

Well it seems my Viking Designer is a retagged Borletti for Canadian market back in the day.
Very hard to get a Manual for it.

Welcome to the QuiltingBoard. Can you post a picture of the controls on the lower right? Also the nose end with the tension unit. Interesting looking machine, I'm going to guess not the original furniture.

Here are the requested pictures

On the controls, I would guess the vertically oriented control is for stitch length, and possibly "reverse" when all the way up. Assuming your machine turns by hand (meaning it's not stuck) you can check by watching the feed dog movement as you adjust this lever. The bottom three, from the top down, 1. Needle position, L C R?, if so looks to be in the R position; 2. stitch width for zigzagging; 3. Reverse, if not the upper most control, but again this can be checked, or maybe it drops the feed dogs, which you could see by moving the lever side to side with the needle at its lowest position and presser foot raised.

With some cloth under the presser foot, put the upper control to a numbered position and turn the handwheel towards you from the top, the cloth should move away from you; if it moves towards you reverse the handwheel direction. Move the upper control all way to the top, turn the handwheel, and see if the cloth moves in the opposite direction. You can try this with the lowermost control also.

Threading the machine will be harder to figure out with the pictures, maybe a picture looking down on the tension unit but angled away from the machine?

Thanks for the information. Will give it a try.

Good call on the needle position.

A lot of times when there are two knobs or levers next to the zigzag control, they are usually to lock the zigzag control.

It looks to me like threading a Singer 15, with the exception that the needle would be threaded from front to back.

I'm not positive about the extra holes in the upper thread guide.

Usually there is a thread guide on the front arm or nose of the machine to guide thread to the bobbin tension guide under the bobbin winder.
