Great focal length, especially for 6x8 back. In 6x7 it is a decent all-around lens. I'm curious to try with 6x4.5 where it is a "norma" instead of slight WA.
I love the floating elements on these KL lenses.

All KL lenses are a bit bulky and heavy compared to those they replace. The 75mm had no precedent. The 75 and 90 are identical (or nearly so) on outside dimensions. But picture quality is enhanced -- watchagonnado?

Awesome lens on a great deal through eBay!
I immediately took it out in the surrounding area of Abbot Kinney in Venice, CA following pick up from the seller. Naturally, I wondered how things would come out until I got the film back!
Image were great!
I took it the next day to a historic park and made photos of buildings and compared with photos at the same time from a KL 90mm lens. The 90mm may have been a tiny bit sharper in this case, but the 75mm was outstanding with sharp detail in distant tree leaves and limbs.
I'm very happy to have gotten this. As a result, I've now bought a 65mm KL to replace my 65mm "C".
Now thinking about the 127 KL to replace my 127mm "C"!
