Hi, all! Some (more) help from the Weihrauch PCP experts needed here.

Does anyone know exactly when the HW 101 was released to the public by Weihrauch, and the date on which it was discontinued?

Also, can someone tell me exactly which major assemblies are shared between the HW 100 and HW 101? I'm guessing the following:
- Stock
- Barrel
- Air cylinder
- Front action block
- Trigger assembly...

...And that the only difference between the two rifles is that the HW 101's rear action block contains a single-shot loading tray, and does not contain the HW 100's magazine-indexing mechanism.
