I picked this machine up on Sunday afternoon, which means the poor thing had been sitting on the shelf for almost 4 entire days during the 50% off green-tag sale at Goodwill. I just couldn't resist. And it came with the manual. I couldn't ask for more. Well, ok, it would have been nice to have a box of accessories hidden away somewhere.
The 543 is almost identical to the 533 down in the basement (I mean, in my repair facility), with the exception being buttonhole settings on the main stitch length dial of the 543.
I put the threading diagram up so others can see how to thread these machines.
This next photo shows the interior of the case top, where the extension table resides when not in use. I think a lot of people don't realize the table is conveniently stored there.
The 543 has a full rotary hook, low shank so it can take most any attachments, and Class 66 bobbin. This may be my new everyday machine (everymonth?), displacing the Kenmore model 385 pictured below.
