The carraige locking mechanism, right side. To open the lock, lever A is pushed to the right (white arrow). Lever B will be lifted and return to lock lever A in the open position. As soon as you lift the carriage out of the V-shape, lever B will go upwards at its right hand side. Lever A will return to its lock position, ready for locking the carriage when it is mounted on the machine. Thereby, lifting the carriage is a one-person job. as is mounting it again. When placing the carriage, the hook at the top end of lever A will give way to the right and snap back to the left and catch a robust pin on the carriage.

Again, the carriage locking mechanism, now with the carriage in place. The ear at A will carry the pushbutton. At C you see the spring that forces lever A counterclockwise. Here you see how lever b is pushed down by its ear by a pin in the top

On lever A in the photo above there is this knob. No thread in the "artificial material" (Dutch for plastic, artificial as 'unnatural', or 'man made' ), In stead, high quality thread in a extra steel nut.

The carriage module in a drawing (thanks, Jaap Horstink). The pins of 010-2569 and 010-2511 fit in the platen with a taper and an M3 thread! The two platen knobs can be very difficult to pull, you need to screw them out against the friction in the tapers!

the platen freewheel clutch in a drawing. Six springs wedge six rollers d between f and sloping surfaces of two plates h. Between the plates H there are the arrows c. When button a is pushed the taper at b will force the arrows c radially ouwards and push against the springs forces. Now, the large knob and the platen can be rotated freely in relation to the ratchet. Again, how elaborate! In the actual machine the set-screw that holds a/b in place is a tiny pin in a tiny tangenially bored hole. See picture

The same trick as on the left side of the carriage: an extra part to close the gap around the paper release lever. The number on the cover indicate the stroke of the paperinjector.

A strikes the bell, B is its actuating spring, C is one of the two spring motors for the mechanised margin stop setting. When the green buttton is pushed and held, the spring motor pulls the (other side) margin stop towards the center, you can move the carriage back to the required position, release the button and you're set

As a retired product development engineer, I am fascinated by the design of electro-mechanical products in which parts move, make noise and, preferably, radiate a little heat. Most preferred are products that are operated by keys, like typewriters, accordeons and pianos.
My genetics and statistics on lifetime expectancy suggest that it is time for me to let you know about the fantastic design, product engineering and manuacturing skills of the generation before mine. I salute mr. Munk for the opportunity that he has created for me to show it to the world. Okay, a bit bombastic.
