Scale focussing a 35 should is doable, which is proven by countless superb pictures taken with the Minox 35.. But longer focal length scale focussing cameras have been available as well, most topping out at 45-50mm.
Be aware though that over time, printing sizes have increased. The ca. 2 1/3 x 3 1/2 inch prints that were the most common enlargement in the scale focusing dominated 1960's have given way to at least 4 x 6 inch. The demand on focusing accuracy has increased accordingly.
Long story short, to get the same impression of sharpness with a 35mm lens on 4 x 6 prints, you'll have to work harder on guesstimating discance than your (grand)parents had to with a 50mm in the old days..
