Well folks I have appreciated and being amused by your comments in equal measure! Madone 9.9 indeed!
I had checked with the Gardai in Kildare and Portlaoise but they have received no calls. The bike, in my opinion, was recently lost as there was no chain rust from either snow or salted roads.
I brought it in the end to the barracks in Portlaoise and we decided to leave it there as it's better to be half way between Cork/Limerick and Dublin rather than the owner having to collect it from either end of the spectrum. - I think the Guard was amused by my inquisition of the type of sheds they had. Hopefully the rightful owner will find it in good repair.
In hindsight, and as a member of Oldvelos(.com), this was definitely the best decision, as if the bike came home to my stable of vintage bikes God knows what would have happened. Just look what happened my Mercian in the recent snow!
