Hi Len,
1103 was home built by my father. I'm not sure on the exact year it was built, but it was built in his garage near Crewkerne in Somerset and spent it's early years at Sutton Bingham near Yeovil. I believe it now has a different rig as the original spars were anodised black. I may be able to get hold of some build photo's if you are interested, although this was sometime ago now, and they have moved to France and back since then!
If you have any particular questions feel free to ask and I'll pass them on.
