Schuco pivot pins

Ah, I remember this one. I've seen this pivot bar only once or twice before. I can tell you now that we don't have an exact match, nor do we have a confirmed substitute. The best option we can recommend is our 26-089.

You'll note that this doesn't have an L shape like your original. It only has screw holes that can mount on the bottom of the sash. You may need to redrill a hole to accommodate this (while making sure not to hit the glass!).

Assuming it fits that way, there's still a question of whether or not it can fit in your window's pivot shoe. The 26-089 has a 3/16" tall by 5/16" wide tip. As long as the cam of your pivot shoe is around that size then I think you could use this. 

Look it over and let me know what you think. I'm sorry that I couldn't make a more confident recommendation!
