I found some more info and now know this too...
According to a site in the UK..."SingerSewingInfo.com.uk." and the subtitled "Singer Sewing Machines 1865-1970", there is a photo gallery showing four versions of the Special Purpose foot I am looking for.
The only difference I see in the two presser feet I was confused about is that the 161612 has a 5mm open slot for the stitching. The very similar 161455 has a 7mm open slot for the stitching."
This makes sense, the timing sounds right for when sewing machines started going to the wider 7mm zig zag from the 5mm common to the earlier machines. 9mm seems to be common nowadays, and I *think* I've read that new machines are going to 11mm. Holy cow, you'd have to use some heavy stabilizer under a zig zag that wide, and think of how much thread it would use.
