Top sash guide

A quick learner from Fleming island FL says:
I bought a house and every single top sash guide is broken. I found the most intact one I could buy from the pictures, there are 4 that could be it, so I don't know which one to order. I don't know the window company or style either. Can you tell me which this is?
Parts I think it could be:
18-127
18-166
18-199
18-044

Thanks for reaching out to us. I agree that our 18-127, 18-166, and 18-199 may be matches for what you have here. These were the first parts to come to mind as well. You'll just need to compare the specifications of each with yours to see which one matches up. There are detailed dimensions on each part's store page that you can use as a reference.
