See post title. I think it's a 380 series. Does that look right?

It would depend on the depth of the shoe. It's hard to tell since yours is damaged. Do you have an undamaged one, perhaps in the other side of the window? If so, I recommend measuring that to be sure.
You should also weigh your sash to make sure you get the right option.
