The main body of the TLR was made out of high pressure die-cast aluminium alloy ("Aluminium Druckguss"). Production of the raw bodies was sourced out to a Munich company from the start. The raw die-cast bodies were made ready for assembly purely by hand. This took quite a bit of time. It involved drilling holes, grinding, and polishing some parts. Look at the side panels for instance. In later years the smaller parts were produced using CNC machines. This is how it was when I visited the factory in 2003. I understand the number of (leased) CNC machines was even greater in recent years but I reckon production of the main body never changed.

Machined camera parts, body included, made by CNC machines will be far better in every respect than ones machined by hand. Even Rollei mostcertainly used CNC machines, not humans, to machine the later TLRs. And before that, they most certainly did not hand machine every body etc. theyused jigs.
