I don't think Minolta used random numbers, that doesn't make sense. The problem is that we just don't know the system and probably it's a simple system (first lens nr. 1, then 2, 3 etc.), but maybe somebody with more knowledge can clarify this.

1. Rokkor Lens Serial Numbers
2. Minolta Rokkor 200mm 3.5 Lens

The Autocords are all alike. However, some details make it possible to differentiate them.

Several models are widespread while others remain uncommon or not found.

The list is not chronological, you'll find the chronology at bottom of this page.
The first model is completely described.
For the following ones, the description in green resumes the changes compared with the precedent model or with one quoted specifically.

Important :

Informations about the Autocord are poor on the WEB. I never found any site to give complete, official informations.

I can not access to Clayton Rye's site ().

Some sites tell about 17 models or more (camerapedia.wikia.com), others tell about 24 (tlr-camera.com).

As one different detail makes a new model, time gave me the opportunity to find more then 17 different models.

These are the reasons why I arbitrarily give unofficial names to some models I discovered throughout my research.

Rokkor Lens Serial Numbers

For those, title is written in blue while remaining logical.
