My old 201, and every 201 I've seen a picture of, and every 201 I've seen in a Singer manual or parts list, has the familiar presser bar adjuster that consists of a "thumb screw" that you turn to exert more or less pressure on the internal spring.  The thumb screw is actually a tube, threaded on the outside, which screws into a hole in the head.  The presser bar itself runs through the center and protrudes through the top, at the center of the knurled thumbnut portion.  You all know what I'm talking about.

But my "new" 1938 201 has a completely different adjuster.  It looks like this.  You press on the top of the thin-walled tube (clearly there's a cap of some sort that's missing there) and the tube clicks further into the machine to give more pressure.  Press on the little lever, and the tube pops back up to its lightest setting.

Is this perhaps some sort of "aftermarket" repair, maybe for heads whose threads have been stripped?  Or a convenience accessory of some sort, for quicker adjustments?  Surely it's not an original Singer part.

And...  anyone know what the little cap should look like?

I’m thinking those pressure cap things like that might have been after market. I hate those. I’ve seen them a lot on refurbished machines. I think I might have done a thread over at quilting board ages ago.

My Universal clone has a pressure release like that.
First pic is of the Morse pressure cap. Second shows the Universal, with thumb release.

The pop up presser foot pressure adjuster is the type used on many refurbs and almost universally used on Japanese machines.

I took one of those adjusters off of my Singer 15-75 when I got it and gave it to a friend to play with. They work fairly well, but don't really look right on a Vintage Singer. They look good on the Japanese zigzag machines, though.

Thanks all.  So, do the replacement adjusters fit into the standard adjuster threads?  That would make them easy to replace.  I was afraid the threads in the head would have been drilled and rethreaded.  Sounds like there's a chance of putting this back to "normal", if I want to.

Oh -- and when looking for an original adjuster -- are most Singer adjusters the same?  Or do I need to find the 201 adjuster, specifically?   Is there a Singer parts cross-reference, which would say which machines any given Simanco number is used on?

I may not do anything at all for quite a while, except try to find some sort of a cap for the top.  After all the adjuster works, and the rest of the machine is no pageant winner.

The adjusters were invented by RevCo, they also made reverse retrofit kit for Singer 66, and ingenious cam knob for reversing Singer 99, calibrated tensions...

The presser foot adjuster was for quick release when darning, and easy reset to normal.

Thanks!!  Those pictures show what the cap should have looked like, and the Revco instructions say their adjuster can be used on any of the 66, 27, 115, 15, 101, or 201 machines, which means I can probably restore the 201 with an adjuster from any of those as well.
