Searching for DSW12

A quick learner says:
I have a push open casement window I am looking for parts for. I believe the window is manufactured in the UK and I think the part number I am looking for might be DSW12. The pictured part in on a lower right and we are looking to replace the upper left. Can you get this part?

Take a look at our 36-045 hinge. I wonder if this could work on your window. Normally, the 36-013-10 hinge is used on casement windows, but yours might be special. Look closely at these two and let me know what you think.
