I have a "Sun Opt. Sun-Zoom Macro 1:3.5 39 ~ 90 mm Multi-coated "
It has a 67mm thread and a K-mount. Very heavily built with a separate macro ring.

The lens you found reminds me very much of the C mount objectives Sun made for cine use.
I love alu barrels!
I own a much bigger M42 135mm f/2.8, branded Porst, that very likely was made by Sun. It's a "silver" barrel lens with typical Sun aesthetic.
I tested it extensively at a flash mob, and I've been positively impressed..
Good build and better image quality than expected.
Got it as part of a job lot. I admit I'd never choose to buy such a lackluster lens, but it proved to be well worth owning it!
The images are contrasty and the MC is pretty decent.
Considering its look, the lens was probably made at the end of Sun's activity (second half of the seventies, I'd guess).
I'd recommend it, if you can find a nice example for cheap.
