I don't know if this one has been noted above or if it is even in the right era/age group. I think it may be:

"....Here is an alphabetical list of account-
ing department men now actually in the
service and their locations as last reported.
Pick out the men you know and write
them. A soldier is always happy to hear
from friends at home:

Melville D. Bailey, Company D, 410th Tel.
Battalion, Ft. Leavenworth, Kans.
....."

Mr Baileys name is the very first one on the list as it is alphabetical.

The listing as an employee of the Illinois Bell Co. at that time serving in the US Army.
I believe the News Letter/Magazine from the Company is from 1917,
It's quite a long read, but with some interesting storys and notes about the War at the time both the Overseas and the Home Front.
Full text of "Illinois Bell magazine"

The 'list' of employees serving is down just less than 1/4 way into the document. No other info given on him.
No other mention of him that I could find in there doing a 'control/F' function and the name Bailey. That's about as much computer knowledge I have.

I would guess and a guess only, that Mr Bailey would have been an 18 to early 20s y/o at the time.
So by the mid 1950's,,55 to near 60 y/o. Just about right for the revolver I'd think.

If it is him, at least a former employee and vocation (Illinois Bell, accounting dept) and a US Armed services record to search for.

And then again,,maybe it ain't him at all.
