I must admit John, my viewing on this particular subject was also brief. I only saw the final block of about 12 bikes in 1941. But there might be others individually interspersed throughout the the whole 4000 bikes. I'll look closer and note down all the details if you want. Ron
John I've taken a longer closer look.
I've found one bike supplied to the Dept of Defense, Dublin and 15 to Dept of Post and Telegraph. There are about 12-15 more to Erne Motors in Dublin. Any bikes in Dublin with a 3 figure frame number must be ex WO London as they used consecutive numbers from 101 to 1451.
I'll send you my list with frame/eng numbers and dates of despatch. Ron
