Thank you Majestic. I appreciate your feedback. Not of much interest to me if mostly a series of names.Vertical writing down far right side:
禱 武運長久 (pray for good luck in battle)
贈 岡田虎夫君 (for OKADA Toraō-kun)
Okada Toraō is the recipient.
The rest are names. Hard to tell if its authentic or not. If its being offered on an online auction site, I don't think I would take it.
