A machine in a full metal jacket and of high quality.
There are some videaos on Youtube on the 1620, look at them before dismantling your machine.

Remarkable details:
- the elegant design
- the elegant mechanical design: you can see that the have been thinking (quality), and you can see what they have been thinking (ingeneous)
- high pressure aluminium diecast housing parts
- lightweight, for a desktop machine
- a sturdy case with two metal strips that hold the machine
- the typical tube type main bearing to guide the carriage, plus an extra rollerbearing to prevent rotation around the tube's axis
- the double paper support that is operated by the right hand support
- the ease of disassembling the machine
- the tendency for the escapement to get stuck, as was the case in this machine. Due to corrosion in this case
- the nice transport lock mechanism: perfect design
- the tiny type face (and the dry ribbon in the type face photo)

For easier engaging when the carriage goes to the left?

There must be a bearing that proevent the rotation of the carriage arond the cylindric tube-bearing.
Here is the roller bearing hiding behind the bracket in the red circle. The bracket, thus the bearing can be adjusted for height of the carriage. Do not forget that when your type is too high or too low. Do not jump to the height adjustment of the segment.

the carriage bearing consists of a stationary outer tube (visible here) and an inner rod, with a ball-cage separating them but allowing axial movment (and a rotation around the rods centre).  The ball-cage moves at half the axial speed of the rod. To prevent the cage from slowly creeping out of the tube there is an arm reaching out of the tube through the slit with a nylon gearwheel that engages in a narrow gear-rack ,about half the length of the travel.

The casing is in thin walled high pressure aluminium diecasting.
This requires an expensive mould to produce, affordable in high price segment yet high volume production. That is rare.

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.
