The Bottom Of The Punchbowl reel

This is a Scottish reel of the type that has lots of crotchets and three of these in succession ending each part (comparable tunes being “Flowers Of Edinburgh” and “The East Neuk Of Fife”). I first heard it played on the record “Fieldvole Music” by English melodeon player Tony Hall, very nicely and not particularly fast.
It’s occurred to me that the setting I’ve put down may not be the standard one, or the best. If I find it isn’t, I hope I’ll edit the ABC’s accordingly.

Irish musicians would play this as a barndance.

I’ve changed the second last bar in each part from |B2dB AFEG| to the following: - |B2dB ABAG|.

I agree with your changes for the 2nd to last bar.
Bar 1 and bar 5 in the ‘A’ music I have as: D2FA d2de |

Bar 2 of the ‘B’ music I have as: | fedc e2A2 | leaving bar 6 as written by yourself.
I use this tune as the second in a a set with ‘Far From Home’ & ‘The Flowers of Edinburgh’
‘Bottom of the Punchbowl’ is also a good companion tune to play with ‘The Dashing white Seargent’ .

Does anyone know a good arrangement of guitar chord for this tune?

Here a version with chords
