In the late 1970s in Leningrad bought a Traveller deluxe writing machine, then one of the cheapest. No samples of fonts were given to any bodies, passports were not asked when purchasing. It was printed, however, mainly all kinds of referrals, graduate works and other small-tailored single-use literature. And for the anti-Soviet self-government, not so many of those who printed, as those who distributed, and they were identified not by criminal data, but by operational data.
The machine, by the way, is still printing properly, although it has been slightly broken.
