Thanks for posting. I have good news and bad news. We'll start with the bad news first.
I'm afraid we don't have this shoe by itself, unfortunately. This goes on an older type of balance that we are not able to provide. It has a unique kind of groove in the bottom (noted by the groove in the "stem" of your pictured shoe), I assume to make it easier to remove the sash.
However, modern balance manufacturers seem to have decided that this groove is no longer necessary, so now balances are made without it. Unfortunately that also means that the new shoes being made can't fit on the old balance, since they don't have a matching groove in their "stem."
Hopefully that makes sense. The good news is, we can still help, but you will need to replace the entire balance system with the modern version. I am thinking our
Series 795 channel balance, but with the smaller, 1" wide
15-194 shoe swapped out for the default one (which is 1-1/4" wide). We can either do this for you as a custom balance order, or you can simply purchase a
Series 795 balance and
15-194 separately and swap them out yourself. It should be pretty easy, they just clip on and off, but let me know how you wish to proceed.
