I was wondering if anyone could tell me which Brush this is?

I have used this brush in 2020 - 2021. It probably is a gouache or pastel dry media brush. Maybe one of Kyle's. However I have been unable to find it in the last few hours. I thought I'd try my luck here.

I don't suppose there is a way to open an older .PSD file and somehow look up the brush that was used?

The brush that is 'active' when I open the below .PSD files unfortunately is not the brush I have used to create these. 

I hope someone recognizes these brush strokes!
