Well, it's been a couple of months and the registration process is ongoing.
I contacted the VMCC a week before Christmas and they responded quick. inspecting and issuing a statement of search by mid January.
Distracted while I settle in to a new job, I only got around to posting off the paperwork to the last week.
I researched the original registration number through the West Yorkshire archive and they provided me with certificated copy of the original entry showing it went to the same dealership as in the Ariel dispatch register, "Charles Sidney Ltd" in Bradford. The dealership manager, Major Scatchard, has long since died but his Son Malcolm sent me some great photos of the dealership from around 1950. (He managed the dealership after his father in the sixties and was very informative, sending me a few photos of a young Frankie Howerd in a DB1). It turns out that Scatchard worked with David Brown in WW2 on Tank gearbox improvements and the Charles Sidney dealership sold Aston Martins when David Brown took over... but were also very active selling motorcycles.
The Charles Sidney name was a WW1 era dealership resurrected in name to sell the cars, but Charles Sidney himself was a quite a Motorcycle competitor and engineer n his day...
Any way... The days are getting longer, the Salt on the roads is being washed away by the rain.... and I my new route to work is 35 miles of B-roads through some fantastic, if rather pot-hole riddled, rolling parts of the Chiltern hills at both sunrise and sunset...
Roll on the spring eh?
