hello,
please dont call this board "PAL Board" ... this one is a converted NTSC Rev.A ( can easily be identified by the PiggyBack Board and the little NTSC imprint on the top-left corner ).
This one here also has some problems generating a colour-Composite Signal .. due to the NTSC/ PAL difference.
A real "PAL Board" has no PiggyBoard and generates a true Colour-Composite output.
I think your buyers should know these differences...

Interest withdrawn.
Thank you @Fook42 for pointing this out. I was more or less convinced that a "real" PAL verson of the Rev.A board actually existed, but if it is still mainly an NTSC board with PAL Agnus and 28.375 MHz oscillator I have to pass on this one.
I own a very early NTSC A1000 with Rev.6 board. As far as I know, the NTSC composite video RCA output is B/W and not colour, not even when hooked up to an NTSC A1080 monitor which I also have in my collection.

okay... for completeness:
the early A1000 are all piggyback-types and for the PAL-countries these were modified by Commodore themself (like the one from @squale) - around 1986/08 the "real PAL boards" were manufactured especially for the european market as the marketing of the A1000 failed in US but was more successful in Europe.
regarding composite-output: please find detailed instructions here ... http://blog.worldofjani.com/?p=6078
you are right, that the RGB output is correct and works fine.. but the composite is not, as the mentioned modifications are not shown on your picture ... but "whatever i say" :roll:
this is the board to be sold here: .. maybe i am wrong and this is not an NTSC board.. but you should look closer on the picture to see "whatever i say"
and this is a "real PAL-board":
