Does anyone have any idea what P.S. 58 stands for?

I know what it means with respect to insurance benefits and 1099R
reporting. But I've never actually understood what the P.S. is an
abbreviation for.

I thought it would have something to do with an IRS event in 1958 but the
earliest IRS reference is for 1955 (Rev. Rul. 55-747, 1955-2 C.B. 228.)

I don't know what P.S. stands for, but those were the predecessors of Reveneue Rulings. (I believe that title was used before 1954.)

How about Pension Section 58 (ruling#?)

Can't let you young whipper-snappers stand around all confused cuz you can't read (it IS in the original stuff ya know).

Any trivia fans out there?

Well squirmers - the answer is....

Oh now I can't just blurt out public schedule now can I? Would ruin all the fun!

Rev. Rul. 55-747 contains the Uniform One Year Term Premiums for $1,000 Life Insurance Protection. This ruling was originally issued as Policy Statement No. 58.

A footnote in Rev. Rul. 55-747:
"This Revenue Ruling reads substantially as P. S. No. 58, Revised, issued on March 7, 1947."

Rev. Rul. 61-157 contains:
"STATUS OF P.S. RELEASES
The following list is designed to give current information as to the status of P.S. Releases issued under the Internal Revenue Code of 1939, which, to the extent consistent with the Internal Revenue Code of 1954 and the regulations thereunder, remain effective, except as indicated:"

There were 68 P.S. Releases from 1944 to 1951. No indication what P.S. stands for.

According to the Finding Lists in CCH Standard Federal Tax Reporter, P.S. means Pension Trust Service.

Was this issued in Boston 1774? Else why is the "T" missing?
