Most BW collectors know there are several types of Moleskin uniforms issued after the Arbeitsanzug was discontinued and before Flecktarn was issued. However, until a recent discussion with fellow members here I had thought there was only 3 different models of the uniform issued from 1963-1991. However, evidence came to light that there were in fact 4 different models issued. A special thanks to PASSAUER8884 for helping uncover this 4th type and providing the picture I used (below) for 2. Modell Jacket.
The uniforms can basically be thought of as two different major types with one significant modification each. Therefore, 1. and 2. Modell look fairly similar to each other, but different than 3. and 4. Modell. Likewise, 3. and 4. Modell have more in common with each other than with 1. and 2. Modell. The exception being 3. Modell Jacket, which has features more similar to 4. Modell but looks more like 2. Modell.
Below are pictures with labels and arrows pointing out various differences. Feature changes are noted, the feature similarities are not. There are probably other differences that are not shown in my pictures. These are just the major differences that are fairly easy to spot.
A note about the dates. If you see a "?" it means the exact date is not known to me, but I'm probably within 1 year of the correct date. If there is no "?" after the date then it is a pretty solid date (production probably overlapped). Trouser dates should be the same as the jackets.
P.S. I am looking for a mint condition 2. Modell Jacket and mint condition 3. Modell Trousers. eBay pictures are horribly unreliable so I will need to get these from a collector who can examine the labels to check dates.
