Acquired both of these in Germany. The first came directly from a German veteran's estate, the second from a German militaria show and was probably also brought back as a souvenir.
There's a book on the Soviet Army symbols in WW2 with the fiirst one shown in a photo illustration in the background. Perhaps someone will recognize it and post a pic and give more info about it.
The second one is interesting because long screw inside the nozzle as an attachment method.
