The so-called "Springschreiber T32" is quite rare and was built between 208 the 1930s and the 1950s. It writes onto a narrow paper strip. It is built so 209 heavily that it is nearly indestructible. As F. Schiweck ("Fernschreibtechnik", 210 1942) notes:<br> 211 212 <blockquote>"The Teletypewriter is one of this most stunning productions and a marvel of 213 mechanical design. It requires the best materials available and is a marvel of 214 construction. According to general opinion, its relability of operation is 215 extremely high."</blockquote> 216 <br> 217 218 Back in those heydays of mechanical engineering the field engineers required a 219 steady hand, good hearing to spot troublesome noises, and, of course, an oil 220 can as well. Their profession vanished in the 1980s.</p> 197 221 198 222 <!-- … … 299 323 typically German devices. 300 324 <br/>The picture above shows the <b>Olympia flexowriter</b> 301 with two pa aper tape readers and one paper tape puncher,325 with two paper tape readers and one paper tape puncher, 302 326 year of manufacture 1962.</p> 303 327 </div>
