Welcome to the forum, you have made a friendly and clear post with good photos, so you are on your way! Here's what I can add, I hope this helps you. Shortly after the second world war, West Germany was allowed to make many consumer goods without paying royalties on patents, as a means to help them recover economically. Bicycles, particularly "lightweight" three speed bikes were a popular product. (These bikes were not light, but that's the designation for skinny tires as opposed to balloon tires.) West German three speed hubs that are more or less exact copies of UK's Sturmey Archer brand were made by the thousands. Many have the brand name Sachs, I suspect yours does too, although I may be wrong. The bikes were all intended for entry-level markets. The most complicated part on your bike is the rear hub, and it's more or less an assemblage of cheaply made parts - the wheels, frame, bars, etc that make that item, the three speed hub, marketable. Whomever made this bike, it was probably sold at a second-tier department store on the downward slide from the bicycle's heyday of the 1960s. Think Kresge's or Woolworth, etc., or possibly a bicycle shop that wanted to make a profit by selling volume, not quality. Check the sticker on the seat post tube, it may be the maker or it may be the dealer/importer, for clues but what we are telling you here is that the similarities outweigh the differences on these more or less generic bikes and parts are parts where a bike like this is concerned. Someone bought this to ride to high school or college and then it went into a garage for a few decades. It's a fun color and seems complete. Service it and do what you can to brighten up the chrome and the paint. Buy some 0000 ("four-ought") steel wool and some WD-40 and scrub the chrome and lube up the paint carefully and you will see some of the luster return. It looks pretty rugged for what it is, but all bikes can be made to look good again if you are willing to do the work. Read the restoration tips section of this forum carefully. If you decide it should be repainted, that's probably the point at which you need to seriously reconsider finding a better quality project/product to spend your time on. As mentioned above, it will never be worth the effort to fix it up for resale. It's worth whatever time you put into it, and whatever enjoyment you get out of it. And that could be quite a lot. A bike like this was at least made by workers who earned a living wage. Bicycles from China are sadly a product that is hurting workers everywhere, and I'm glad to say your bike isn't contributing to that trend. Bikes made in Taiwan however have now dominated the market as they are often cheap to produce but of high enough quality that they will last the lifespan of a typical bike user and either function as a good enough product to get by on, or bring the owner into the market for a better quality product. In general it's a tougher call to decide what to think about the flood of bikes from Taiwan. They are getting people out of cars, and that's great. Any bike that gets ridden means one less car trip and I am personally all for that. This group is mostly for old collectors of American made bikes from the heyday of the 20th century and it's a friendly place, we welcome you. But most of us wouldn't give a bike like this a second glance. It's just what the demographic and hobby dictates. You average garage sale bike seller knows nothing about bikes other than they are old and in the way, and we've all been to so many garage sales that we wait to find something cheap to buy that has some better history and quality and collectability to it before investing our time on it. But if you can appreciate the bike for what it is, by all means get it going and ride it to your heart's content. Lots of people would jettison the steel wheels and find some aluminum wheels that are from a Taiwan bike and ride this thing as a single speed, or a three speed after upgrading the brakes and the cranks, too. Everything that rotates on a bike takes effort and so if you can lighten or improve the quality of those parts first, the bike will perform better. That means wheels first, tires and drive train next. The fact that the frame is steel and relatively heavy isn't such a problem once you get the bike moving. I don't know where you live but if there is a community bike shop nearby, check it out and sign up for a clinic on refurbishing a bike, it's easy and you will learn a lot and probably make some new friends, too. Good luck with the bike, I love the color. You would be surprised how little it might take to get this thing to a state where you enjoy it every day.
