This is the place where Stones fans can advertise anything for sale, wanted, trade or whatever, from fan to fan. Advertisements are for free. To see the old ads go here.
A year ago or so there also was a discussion whether a remastered version of any official track would be official considere as well. Although the reworked track is different than the Original, it still must be considered as official. I can call into memory some Mickboy remasters. Don't know for sure how to value these 25x5 tracks.
(btw; I did get this OBR without these tracks 11,12,13) Lateron I did trade the full number of tracks).
