Braun Era

Newly Discovered Prototype Models

During my examination of the Braun archives while visiting the Reha Werkstatt Oberrad (RWO) in November of 2013, I came across photographs of 3 digit numbered models that I had not seen before. These appear to be packaged prototypes in cassettes which do not appear to have been productized or sold. I have not seen them in any Braun catalog. The verbiage in three languages was a hallmark of the cassette versions which followed the Styrofoam mold packaging versions. One model (111) shows a motor with N and S magnets which Braun never released.

All of these prototype models used a more expensive hinged cover arrangement. That feature would be retained only for the Ausbausystem 3 and System 300 models which were productized.

These seem to have only appeared at the Didacta - Europaische Lehrmittelmesse show in Hanover on June 7th through the 11th in 1968. The photo below is from that show. To my current knowledge, these models did not appear again at any other show and were not listed in price lists or shown in catalogs.

G√ľnther Stabe pointed out the fact to me in a recent email that the 100 and 202 models were listed a Dutch price list from 1969 that I had acquired and shared with him. There are no extant photographs of these Dutch models so it is difficult to affirm that these are the same ones shown in the photos below.

Here are the 'missing' prototype models:

The Model 100 was akin to the Grundsystem model in that it was the basic model that subsequent models would build upon.

The Model 101 required to model 100 to complete experiments focused on radio techniques culminating in the AM radio experiment. It appears that a two section antenna was also included in this model. This antenna never appeared in any other LECTRON model, Braun or otherwise.

The Model 102 focused on lighting and heating techniques and required the 100 and 101 models to complete its experiments.

The Model 111 used the motor and N and S magnets for the first time. This was the first and last time, to my knowledge, that these parts were used in a Braun model. They would surface again during the LECTRON - MW Era.

The Model 1/200 reviews low frequency circuitry, and examines stereophony - a topic never examined or discussed in any of the other Braun models or instruction manuals. Note that the 100, 101, and 102 models were required to complete the experiments for the 200 model.

The Model 2/201 examined control and measuring techniques. Note that the 100, 101, and 102 models and the model 200 were required to complete the experiments in the model 201.
