Think it's even more than a 'nice piece of history', a valuable piece of history. it's easy to undervalue something, when your the owner, but in this case...it's rare, added to which, it's a pretty/nice looking 'bit of kit. thank you for sharing it, albeit only a photograph.
I have made good most of the failings with this project, and hope to have it start up today! I have several photo's to upload. Hopefully I will be able to share repair knowledge for other owners of this model bike.
