I got in touch with your Dad a few weeks ago. I was stationed with him in Okinawa before he went STO, and saw him during an exercise when he was at SOCPAC. Good luck finding one...I've got the opener itself I could send you...you'd just have to get the PJ flash etched into it...shouldn't be too hard to find someone to do that. PM me if interested.
The real test comes when all strength has fled, and men must produce victory on will alone...
