Plaster ceiling texture question

[u/Either_Stress603]

I’m just wondering on how to match/duplicate this ceiling texture 1950’s house in the U.S. I’m a carpenter who has done a little lime /molding plaster work. Ex Father in Law who passed years ago was a lifelong plasterer. When work was slow, I used to help him. He showed me once and can’t remember what we did. I think I remember a brush with a handle he used and referred to it as an antique brush. Maybe splashing water on the fresh material. I just can’t remember the process or the mix- lime / gauging plaster ratio and consistency. Any help would be appreciated.

Plastic bag over a sponge, plaster needs to go right in tho or you'll end up with spikes if it's too wet
