The Novar on my 521/16 has a nice feature to assist the shooter. There is a little dot on the distance ring, just beyond 8 meters; another on the aperture, just short of f11. I shot a roll on the street using this setting and the whole thing came out real nice.
That is how I know what the hyperfocal distance is!
The Novar was the cheaper option not as good as the Tessar wider open but as has been said abopve is usuallya good performer stopped down, but then that's true of any triplet lens.
The Novar on my Ikonta is unuseable due to poor contrast and low resolution, the 1930's versions tend to go soft with age due to the type of glass used, I have two spares new ones , the first is again 1930's in a great Compur shutter but the lens looks hazy the other's a coated post WWII lens which should make the camera useable at last
With a 105mm lens, it should be a 6x9 camera, which is a particularly fun format because you can contact print it. The resulting prints look small to a modern viewer, but they were the normal print size for a generation or two, before 35mm took over the world; you can still find little cheap frames in this size at craft stores and so on.
Also, the larger format can really show off the "inferior" properties of the triplet lens---you're likely to see a lot of vignetting and interesting softness in the corners, especially at wider apertures. I think that's part of what creates the "vintage" impression; it can also be quite effective at drawing attention to a central subject.
There should be a model number---for 6x9, I think it's always 520, 521, or 523---embossed in the leatherette at one end of the body. That'll get you an approximate date range, if you care.
