It says
祈武運長久 (pray for good luck in battle)
為武田定治君 (for Takeda Sadaji-kun) (multiple readings possible)
The remainder are names. I can't tell it its authentic or not. There is a similarity to all the names, there is nothing particularly unique about it - no date, no location, no presenter, no other identifying clues, which makes it hard to pinpoint, and makes one think it may have been fabricated after the war. That's my initial impression.
