Original Signed Print collection SCHINDLER, WAUCHAU,DUNSTEIN, Austria

i Have a set of 3 Framed prints, but i wanted to show all photos of each so they are listed separately.
The signature is SCHINDLER, but I cannot make out the words before the last name.
I researched without success. Perhaps someone can tell me about this artist?
They are all definitely from the 1800's and have original frames, matting and backing.
I am not sure if they are 'original', or 'original prints' or "?" I did not want to remove them
from their original frames or remove backing, lest I destroy something valuable.
See photos of backing, torn, frayed, totally brown and dried out paper.
Also, glare from glass visible in most photos.
These were from a bachelor Uncle's estate who served in Europe during WW II. He
most likely brought these back, as I am sure collection they were not purchased here in US.
Frame is 10 1/2 X13 1/2"
Drawing is 5 1/2 x 7"
Please view all photos and judge condition for yourself.
