Hello everyone,
I decided to present a diorama with action at Hangar 2. For this purpose I began to collect information on the building of the photos that I found. However, they noticed that some of the hangar is wearing some kind of material, much like canvas or perhaps sheet metal (probably lead). It comes to the front facade. The side walls are also implemented as, if similar material, but may be of wood siding. Photographs taken later showed that at the end of 1917 the building was completed in this way. For I delivered period, however, this method is partially used. For comparison Hangar 3 is made entirely above said manner.
I would like to ask you for more information if you know what exactly used in the construction of Hangar 2?
Thank you in advance.
This is a picture of the hangar from the spring of 1917:

These are pictures of the hangar in the summer of 1917:



And these are from the end of 1917:
