Hmm. I've gone looking for a pic, link...can't seem to find anything. It attaches to the screw and the pillar and moves when the screw is turned, giving you a relative length.

I'll keep trying to find a link.

This has the screw type adjustment with no gauge

This is the later type with the adjustment arm and gauge

The Interesting Singer with the Revco on the screw?

Yes, that's it, exactly!

Oh, Quincunx, thank you! I followed one of the links to this post with a great image:

Thanks for searching, KRA :) .

There's some token Tolkein going on around here!

Rodney gave you good advice. My first older machine was handed down to me, a 15-91. Eighteen months later I purchased a 66 because I wanted a treadle. Like you I want my sewing room to be functional not cluttered. Each of my machines has a purpose. I look and it tugs at the heart. I pass on buying because someone may need it.

Caroline, I had not seen you on here before. I hope those machines are in GF. I too do not like a cluttered room, but after my 201 Centennial purchase, it is getting that way. I do have one of my Featherweights sitting on top. I think we need a Valley Antique club so we can get together and discuss what we have and learn from each other. Hillsboro? Thanks for your post.

Yes, Veinurse; I'm new here. I discovered this site while searching for a more user-friendly quilting forum. Then I found the Singer 15-91 and learned just how informative this site can be!

We are practically neighbors! I live in Larimore; it's 138 miles from my house to the Barnes & Noble bookstore in Fargo. Hillsboro would be a great meeting place. When I make my yearly trek for Fargo Shopping I always stop there for a stretch break on both going and returning routes.

Yes, the Singers - 99K and 66 - are both at the Dakota Boys' Ranch Thrift Store, Demers St., Grand Forks. At least they were still there last week when I took the photos. I bought the 15-91 at the Valley ARC Thrift Store across the same street.

If I ever get this house cobbled together I should have more time to do some thrifting/antiquing/junking in Fargo!
