Ruger letter for my dads Ruger 1957 standard

[akmania]

I sent for a letter of authenticity for my dad's 6" standard which my son has now. I'll post a picture of the letter. Does anyone know anything about where this was shipped?

Probably the PX for Fort Lewis and McChord Air Force Base if I had to guess.

Yes, a soldier or airman ordered it be my guess.
