I have had a sewing machine business since 1989 and have seen some of these machines come in for cleaning and oiling.
Machine with 'odd' name brands like yours and others were made in Japan by Toyota for hardware stores, department stores, etc.( Or a 'sticker' that says Approved by Good Housekeeping.)
All metal, which is good these days, and will keep running with hardly any repairs. The motor belt can wear out, but you can replace it easy with a Singer Stretch belt or even better, buy a 'cog' belt when you take it to a shop and have a dealer/repair person put it on for you and then he/she (better ask them to do this) can check the motor brushes.... there are brushes (in the motor) that can be taken out and examined. If they are worn down they can be replaced. (Sometimes I had to 'make the fit' but sanding them down a bit.)
If this has a bobbin winder on the top it can be a problem if the spring goes. But a good dealer has parts from other old machines that may fit. But I have never had anyone with a problem with it so far. Springs were made to last... not like some of the parts today.
If this is a zig zag machine it was no doubt made in the 1950's or even 1960's.
Zig Zag machines were being manufactured also, but very expensive and Name Brands. Hope this helps. Judy

Metal tag on side says 30 precision deluxe. can anyone tell me what its worth or where to find out without fee.
Thanks,

Hi, I was wondering does this need a pedal in order to work I found a De Luxe 400 of the same thing in a turquoise color but no pedal. So I was unsure if it needed one. I have newer sewing machine about 10 years old and it is a singer. But this was in the cabinet with a Free Sign on it on the side of the road 1 night and so I stopped and grabbed it up. But I know nothing about it. I hope to find something out. It is really neat! :) Thanks for any info ahead of time...

I have a Good Housekeeper machine it will wind the bobbin but I can’t get it to sew! How do I clean it and check for problem? Thanks it’s a beautiful machine..

I have the Good Housekeepers model 277 and I can’t get it to sew, the bobbin will wind but nothing, I have taken the hand wheel off oiled it then tried and it worked then when I out a needle and thread it didn’t move! Help!

I can’t help you, but what a piece of art !

That’s why I wanted it, it’s a gorgeous machine and it making me crazy can’t find a Manuel

Needs to be taken to a reliable repair person. May oil in just one place to get it moving again.
