The Ausbausystem für Buchlabor or Red Book was the expansion model made by INELCO for the Braun Buchlabor model distributed outside of the Italian marketplace. The INELCO trademark dark green plastic mold packaging was used. The Red Book is a very rare model in the Lectron System product line. It was created as an expansion kit to essentially convert a Buchlabor model a Grundsystem 8000 model.
This is a Lectron – MW Era model. The Ausbausystem für Buchlabor did not appear in any known Braun catalog or price list. Lectron – MW Era documents referred to the Ausbausystem für Buchlabor model but the photo in the brochure showed the blocks stored in a cassette tray with the usual packaging and cardboard box. The was no visible company name or marking anywhere on the Red Book’s packaging aside from the green tri-language sticker (so I thought at the time of the Red Book acquisition date in 2012 – further acquisitions helped me identify the originator of the Red Book).
The tell tale logo on the right of the side panel identifies it as a Lectron-MW era model despite the other Braun branding.
The reader will remember that original repackaging was often used until exhausted before being replaced by new packaging as shown below. Lectron-MW would keep the identical graphic on all of its subsequent (after the Braun supplies were exhausted) packaging and would distinguish the model type using different colored sticker tags on the front cover and side panels.
When I acquired my own Red Book, it came with the standard 90 experiment instruction manual but in Italian with the 1100 learning and teaching cards in German using the A5 size format. I just thought that perhaps this was a simple mistake along the ownership chain and I substituted the Italian manual for a German one. That theory was further validated by my research colleague Mr. Günther Stabe. He also possesses a Red Book and his came with a German version of the 90 experiment instruction book.
I was looking at the Red Book during the morning of June 13th, 2013 (I guess I had nothing better to do with my time, lol) and noticed a small black line to the left of the green sticker on the bottom left side of the cover.
At this time, I was not aware of the INELCO origins of the Red Book. Peeling back the label, imagine my surprise when the following was revealed.
