Ok, well I'll start by saying I could not find what you wanted at this time.
I got the same bunch of Singer stuff until i typed "new home case latch -singer" (without the quotes)
I did however find these which may work. The seller says singer, but they all tend to say that anyway....

Or I can make you a set...
