How do I replicate this misty spray paint texture/pattern?

Question

I am restoring some old Microscopes and the existing coatings are in poor shape. I would like to strip the castings and refinish them to look as original as possible. Unfortunately, I am unable to determine what coating or process was used to achieve the fine water mist texture as shown:

Is there a paint or process available to achieve something at least close to it?

If the material is metal, one can use a wrinkle finish powdercoat to accomplish this result. It's not quite exactly the same texture, but wrinkle finish powdercoat may qualify in that it's random and irregular.

Using search terms "texture powder coat" provides a number of similar finishes, including hammertone and silver vein, the latter shown below:

If there is a powder coating service in your area, they can advise of the available finishes. You can also purchase a home powder coating system which can be used with an inexpensive (yard sale) toaster oven for small parts.

The true way to do it is as fred_dot_u (upvoted your answer!) suggested - a powder coat. However if you did want to hack it, you could spread a very thin layer of elmer's glue or a spray adhesive and roll the surface in a light layer of sand and let dry for a couple of hours. Once fully dry, spray paint it over. That should give you a similar sort of texture. My husband uses this method when he paints mini figurines and mini landscapes, and it works well.

The best way i could think of getting this would be to hold the spray paint far back from the object. This will usually result in some sort of bumpy texture like the one pictured. The only real way to do this would be a special powder coat, but im assuming you dont want to pay for that. You could also try stippling with a brush and thick paint. My last idea would be getting a grip spray paint/anti slip paint. These are the only ways using spray paint I can think of to get that texture.
