There was no block or content difference between the Braun and Lectron, GmbH – MW era 1100 family models.
The 1100 model together with the 1101 model formed the 1102 model.
The 1100 was sold in a nice portable black case. A small ground plate was included with cabling.
Later in the 1100 model’s life, a single block electrical solution was substituted for a 2 block electrical solution.
The 110X models as shown in the brochure.
