With their combined N and +IP purchase tax codes, your copy, paneity, must be right from the time when the 66% purchase tax rate (+IP code) was replaced by the 50% purchase tax rate (N code) in April 1953. The blurrier labels both have N codes, so are from Apr. 1953-Oct. 1955.
Thanks for the info PhilMH . I was aware the matrix numbers don't potentially mean much more than what you say. The only discography mention I can find lists sides as per the entry above in the order I've used.
I can't find out which take this as I can't play this or any other 78 at the moment. If I see something like this in the local charity shop I'd prefer to give it a home before it gets broken by the browsers (the most likely fate in the shop where I found it).
I just remembered that I came across a Louis Armstrong discography a few months ago, so here are the session details:

The two takes of SLEEPY TIME are identical, except that the second (used on all reissues) substitutes the word "people" for "darkies". "
You can't necessarily go by the matrix numbers when determining the A-side - in US Decca's case (where these comes from), the matrices simply reflect the order in which the songs were recorded at the original recording session, which looks to have been in Los Angeles. Anyway, "When It's Sleepy Time Down South" was the charted side in the USA, entering the chart on Jan 17th 1952 and peaking at #19 (Decca 27899). Louis first recorded the song in 1931 (Okeh 41504). I don't have a UK release date, unfortunately, because Paul Pelletier's Brunswick listing started at 05000 (November 1952). It's always possible that UK Decca/Brunswick changed the A-side for UK release, but who knows at this late date?
I went by the matrix numbers for A/B or Side1/Side2 when adding this, though I see on 45cat the US 45 rpm release has those same numbers but with the songs in the reverse order. Looking elsewhere I see that Louis Amstrong recorded "When It's Sleepy Time Down South" many, many times.
[On the US 45rpm, the "Sleepy Time Down South" side is marked as the B side with a star behind the matrix number. So you entered the songs here in the correct order. Mod.]
