Thanks, again, factfndr54
According to this information, these searchlights were manufactured from 1942, based on a Siemens model....
Perhaps it was based on the German Flakscheinwerfer 37 but it is not identical....The structure that holds the lamp itself is clearly different, apart from the fact that the German model had detachable trailer axles while this Swiss model did not.....
On the other hand, I have found this other image (image 3) of a Swiss searchlight, but in this case with detachable trailer axles. The lamp seems the same of the other model but the carriage and trailer is clearly different....
In summary, I think that there are at least three different models of searchlights in use with the Swiss during WW2:
1: the Siemens model with non detachable 2-axles trailer
2: the model manufactured by Color-Metal A.G. with non detachable 2-axles trailer
3: the model with with detachable axles trailer
