Hello comrades, I have an appointment booked with the Registration authorities. The government department I was dealing with told me that in place of a V5 all I would need is a letter with the bike credentials from a genuine classic/vintage motorcycle club here in Ireland.
I have found a VJMC here in Ireland and they are only charging me 40 euros for the documentation. Hopefully the appointment goes well in 2 weeks time with the authorities and I will have her registered. Thanks to everyone who helped thus far especially Andy and Wayne_Gardner (Nick) who have been super helpful through email correspondence.
